VPNGY Protocol and Routing Reference

FOUNDATION

Build a connection decision model

Protocols, routes, and egress locations are different things

Connection quality usually depends on several layers. The client reads subscriptions, establishes sessions, and applies routing rules; the protocol defines encapsulation, handshakes, and recovery after connection changes; the route determines how data travels from the local network to the remote entry point; and the egress location determines where the destination website sees the request coming from. Mixing these concepts often leads to blaming the protocol whenever a page loads slowly, or repeatedly changing regions when one app cannot connect. In reality, an app issue may come from routing rules, a slow connection setup may come from DNS resolution, and sustained slowdowns may come from route congestion. Identify the layer first so each adjustment has a clear direction.

A protocol cannot erase physical distance. The more complex the path between the remote region and your local network, the more noticeable round-trip delays usually become. A route also cannot fix incorrect client rules. If related domains are assigned to different egress locations, text, images, and login APIs on the same page may take separate paths, leaving some content working while other requests time out. An egress region is not the same as a route type either: the same region can have direct, relayed, and dedicated entry points, while the same route type can terminate in different regions. First identify which region the target service requires, then compare the topologies and protocol combinations available there.

Break one connection into observable stages

For troubleshooting, divide the process into client preparation, name resolution, session establishment, sustained transfer, and connection recovery. Client preparation covers subscription validity, the system proxy, and rule matches. Name resolution determines whether the target domain receives the correct address. Session establishment shows whether the handshake path is working smoothly. Sustained transfer reveals bandwidth contention, jitter, and packet loss. Connection recovery appears after network changes, device wake-up, or brief outages. You do not need to capture complex packets to make an initial distinction. If every app fails, check the client and local network first. If only certain sites fail, check routing and egress. If the first load is slow but later requests are stable, focus on resolution and handshakes. If things start smoothly and then buffer repeatedly, the issue is more likely in sustained transfer.

This layered approach reduces irrelevant variables. Change one thing at a time: fix the target region first, then compare routes; fix the route, then compare protocols; once the protocol is confirmed, review the rules. If you change the region, client mode, and protocol together, even an improvement will not tell you what actually helped. The next time network conditions change, you will have to start over. Technical selection is not about finding one combination that is always right, but about keeping a decision path that can be explained and reproduced.

Build a baseline environment

When comparing connection setups, keep local conditions as consistent as possible. Use the same access network, device, and target service, and pause other high-bandwidth tasks. First record qualitative observations such as whether a connection can be established, whether pages load completely, whether long-lived connections remain active, and whether service recovers after a network change. There is no need to chase a single speed-test result. Instantaneous speed is affected by local downloads, wireless interference, target-service load, and cache state, so one result cannot represent sustained route performance. For office work, development, and chat-based apps, maintaining a stable session is often more important than a short-lived peak; for large files and streaming, sustained throughput and buffer recovery matter more.

VPNGY provides 110+ countries and 150+ routes. Clients support Windows / macOS / iOS / Android / Linux, with unlimited devices online at the same time. Broad coverage gives you room to compare, but more routes does not mean you should test the entire list every time. A better approach is to keep a small set of candidates for each target region and choose stable combinations for each use case. See the routes page for regions and route types, and the plans page to compare monthly subscriptions and data packages. No email address is required for registration; a username and password are enough. Keep your account details secure.

PROTOCOLS

Trade-offs of common protocols

Shadowsocks: a straightforward baseline

Shadowsocks is relatively simple in structure, has mature client implementations, and usually keeps resource use easy to control. It works well as a baseline for protocol comparisons: if a route continues to lose packets or cannot establish a connection for a long time with this relatively direct transport, the issue is more likely to be the local network, route path, or remote entry point than a lack of additional settings. For web browsing, ordinary downloads, and rule-based routing, it generally provides clear and predictable behavior. Its limitation comes from that same simplicity: it offers fewer tuning options than other solutions when you need more complex transport combinations, connection multiplexing, or adaptation to unusual networks.

When choosing Shadowsocks, do not stop at the word “lightweight.” Client implementation, supported encryption methods, DNS resolution paths, and system proxy modes all affect real-world results. On desktop, running several proxy tools at once can cause port conflicts or leave stale system-proxy settings, making the protocol appear unusable. On mobile, system limits on background activity can make connection recovery slower than a foreground test suggests. It suits users who want a simple, stable setup, have limited device resources, or want fewer configuration variables. It is also useful during troubleshooting to confirm a route’s basic connectivity.

VMess and VLESS: different architectures, with client support as the key factor

VMess combines authentication, time-related checks, and transport organization within a complete protocol system, and is widely supported by common clients. Its strengths are a mature ecosystem and flexible combinations, making it suitable for users who already work with compatible clients and need to manage several types of routes together. The trade-off is a longer processing chain and more configuration fields that can become inconsistent. A badly incorrect device clock, mismatched transport options, or incomplete subscription conversion can all cause connection failures. In that situation, updating the subscription and restoring the service’s default configuration is more reliable than manually editing several parameters.

VLESS keeps the protocol layer more streamlined and delegates security and transport capabilities to outer mechanisms. The real-world experience therefore depends more on the complete combination than on the protocol name alone. The same VLESS setup can behave very differently with different transports, client cores, and route paths. It suits cases where client compatibility is clear, subscription parameters are complete, and you want to keep the protocol layer lean. Treat “VLESS plus transport plus route” as one system rather than using VLESS alone as a speed label.

Trojan: mature secure transport, with compatibility as the priority

Trojan is usually built on mature secure transport, making the handshake and certificate validation important parts of a normal connection. Its behavior is clear and it suits scenarios that require reliable sessions and broad client support. The troubleshooting checklist is equally clear: the system clock, DNS resolution, certificate validation, and client transport settings must agree. If the target domain resolves incorrectly on the local network, or the device clock is far enough off to affect validation, the visible symptom may simply be an endless connection wait. In that case, switching routes repeatedly may not help; verify the basic environment first.

In terms of resource use, Trojan’s secure transport adds necessary handshake and encryption work, but on modern desktop devices the more important factors are usually the number of connections and the client implementation, not the protocol name itself. Many short connections, frequent reconnects, and overly granular app routing can create extra wake-ups with any protocol. On mobile, watch what happens after the screen locks and after the network changes. If the client maintains sessions and reuses connections correctly, everyday use is usually smoother. If apps keep creating new connections, both power use and waiting time increase.

Hysteria2 and TUIC: different approaches for unstable networks

Hysteria2 and TUIC both place greater emphasis on transport performance amid packet loss, jitter, and network changes. They are not automatically faster in every situation. Instead, they use congestion and recovery strategies that differ from traditional reliable byte streams, aiming to keep useful data moving more continuously when path quality fluctuates. This can be valuable on mobile networks, shared Wi-Fi, or long-distance paths. At the same time, they depend more heavily on the client core, network support for the transport, and matching server parameters. If the local network handles the chosen transport poorly, the result may be less stable than a basic protocol.

Hysteria2 is a better fit for sustained transfers where maintaining throughput in a changing environment matters; TUIC is often used when concurrent sessions and fast recovery both matter. Neither should be tuned by stacking manual parameters for an aggressive-looking configuration. Congestion control needs room for path feedback. Pushing too hard can increase queueing and make interactive requests wait longer. For most users, the subscription’s default values are preferable. Comparing session stability, recovery after network changes, and video buffering is more meaningful than copying unfamiliar settings.

TRANSPORT BEHAVIOR

Connection setup, reuse, and resource overhead

Connection setup speed is not determined by the protocol handshake alone

What users perceive as a “slow connection” usually includes several waits: the client reads its rules, the system passes the request to the proxy, the target domain is resolved, the route entry is reached, the protocol handshake completes, and a session is established with the target service. The protocol handshake is only one part. If the first visit is slow but similar requests become much smoother afterward, DNS caching, session reuse, or target-service caching may have taken effect. If every new page repeats the delay, check whether connections are being closed too often, whether the client has disabled reuse, or whether the local network keeps changing egress paths.

When comparing protocol setup speed, avoid counting the target website’s own response time as part of the protocol. Start by watching stage-specific messages in the client connection log, then cross-check with several different targets. If only one site is slow, do not immediately blame the route entry. If every target pauses during the handshake, the protocol combination deserves closer inspection. Desktop browsers may maintain connection pools, while command-line tools, development environments, and embedded web views may use different network stacks, so different behavior on the same device is not contradictory.

Connection reuse reduces handshakes, but can amplify a single-path failure

The basic idea of reuse is to carry multiple app requests over an existing transport session, reducing the cost of repeatedly creating connections. For many short requests, web resources, and development-tool APIs, sensible reuse can shorten waits and reduce processing overhead from frequent handshakes. More reuse is not always better. If the underlying session carrying several requests becomes unstable, all of those requests may be affected at once. If a large transfer occupies the send queue, interactive requests may also be pushed back. Client queue management and core implementation therefore matter greatly.

To judge whether reuse is suitable, watch for two patterns. If disabling reuse makes small page resources noticeably slower but leaves connections more independent, reuse was genuinely reducing setup cost. If enabling it causes large-file transfers to slow chat, terminal, or meeting traffic, the shared queue may not suit the current mixed workload. Most users do not need to switch this option regularly; subscription defaults are usually safer. Test reuse as a single variable only when the issue can be reproduced consistently.

Encryption, encapsulation, and device resources

Protocol processing uses CPU, memory, and network wake-ups, but actual resource use cannot be ranked by protocol name alone. Whether the client core is native, whether the system provides hardware acceleration, the number of rules, concurrent connections, and log level can all change the result. On desktop, continuously writing detailed logs may add disk activity. On mobile, keeping the wireless radio active frequently often affects battery life more than a single encryption calculation. “This protocol always saves power” is therefore not a reliable conclusion; judge it together with the client and usage pattern.

When device resources are limited, remove unnecessary variables first: disable long-term debug logging, avoid running several tools that take over the system proxy, use a clear rule set, and reduce pointless automatic speed tests. For protocols, prefer options with mature client support and stable connection behavior. For long downloads, a steady session is usually more efficient than repeatedly rebuilding one. For occasional browsing, entering sleep promptly and recovering cleanly after wake-up matters more. The goal of resource optimization is not to make the client completely inactive, but to avoid repeated failures and useless retries.

DNS resolution and routing rules need to be considered together

Whether DNS resolution happens locally or through the proxy path directly affects the target address and routing result. If rules make decisions by domain but the app first converts the domain to an address locally, later connections may contain only address information. The client then needs mappings or address rules to preserve the original intent. Sending all resolution to a remote endpoint can also increase the wait for the first request. The right approach depends on the client and use case; the key is to keep the resolution path consistent with the routing rules.

When troubleshooting a specific service, place its related domains in the same rule group first so the main site, static assets, login APIs, and media domains do not split across different egress locations. Do not infer the full dependency set from the site’s main domain alone; browser developer tools or client logs can usually show which domain owns a failed request. Developers should also remember that command-line environments may not inherit the system proxy and may require proxy variables to be configured according to the tool’s documentation. Examples should use only local loopback addresses; never put a real subscription URL in a script or repository.

# Used only to check whether proxy variables are explicitly set in the current terminal
printenv | grep -i proxy

# The example subscription address must use a fake value; do not include real credentials
SUBSCRIPTION_URL="https://example.com/sub?token=YOUR_TOKEN"

The commands above show the current terminal environment and do not modify system settings through the client. If the browser works but command-line requests fail, first check whether the tool reads the system proxy. If the command line works but the browser does not, check browser extensions, separate proxy settings, and secure-DNS options. This comparison narrows the issue from “the protocol may not work” to a specific network stack and avoids repeatedly changing routes.

ROUTE TOPOLOGY

Direct, relayed, and dedicated route topologies

Direct: a simple path that depends more on public network conditions

A direct route means the device reaches the remote entry point through the local and public networks without an intermediate relay. Its structure is simple and has fewer scheduling layers, so it can provide a direct connection when the path between the local carrier and remote entry point is good. It is also more exposed to changes in public routing. The same region may use different intermediate networks depending on the access network and time of day. Once a path detours or a segment becomes congested, latency and jitter change. Direct does not mean low quality; its controllable range simply differs from relayed and dedicated routes.

Direct routes suit stable local networks with clear paths to the target region, or situations where a simple topology is useful as a troubleshooting baseline. When a problem appears, compare another entry point in the same region. If direct routes in that region are broadly affected while relayed routes work, the public path from the local network to the remote region is more likely at fault. If only one entry point is affected, that entry point or its upstream path may have changed. Direct routes are often enough for temporary browsing and ordinary downloads. For meetings, remote terminals, and other work that cannot tolerate frequent path changes, keep more controllable alternatives available.

Relay: add entry-point scheduling to improve the first leg

A relayed route first sends the connection to an entry point that is closer to the user or follows a more stable path, then forwards it to the target region. It adds a forwarding layer, but may reduce public-network detours through a better first-leg connection. Do not judge a relay by simply counting hops. One additional segment is not necessarily slower; what matters is whether it replaces a poor public path. If direct access to the remote region is jittery while access to the relay entry is stable, the relayed route may provide a more consistent overall experience.

Relays also have limits. The relay entry itself may be a shared resource, and congestion on either the first or second leg can affect the connection. If scheduling does not avoid a problematic upstream path quickly enough, the user will still see instability. When troubleshooting a relay, distinguish between “cannot reach the entry point” and “the path from the entry to the target region is failing.” If every target region using the same relay entry has problems, focus on the entry. If only one target region is affected, the issue is more likely on the second leg. For users, the most practical method remains fixing a region and comparing topologies instead of switching randomly through the entire route list.

Dedicated: focus on path control and peak-hour consistency

Dedicated routes emphasize a more controllable transport path, usually reducing unpredictable detours and congestion in the public network. Their value is mainly in sustained stability, jitter control, and consistency during peak hours, not just a peak result from one test. For remote meetings, development connections, sustained uploads, and tasks sensitive to continuous responsiveness, path control often matters more than instantaneous bandwidth. IEPL dedicated routes are an example of this topology. Selection should still account for the entry region and local access quality.

A dedicated route cannot fix local wireless interference, device sleep, or an outage at the target service. If packets are already being lost between the device and the home router, a stable downstream route cannot restore the first-leg data. If the target service has requirements for account region or session environment, simply switching to a dedicated route cannot replace the correct egress location. Think of a dedicated route as reducing uncertainty across regional paths, not as covering every issue in the connection chain. When something goes wrong, check the local network, entry point, regional path, egress, and target service layer by layer.

Let the use case determine the egress region

A geographically closer region usually helps reduce propagation delay, but the use case may take priority. Regional content, account services, and enterprise systems may require a specific egress region. Meet that requirement first, then choose a topology within the region. If the use case does not require a particular region, start with an entry point that is relatively close and stable. Frequently switching between distant regions can make login sessions, content-delivery caches, and app risk controls reassess the environment, and it makes troubleshooting harder.

VPNGY’s routes page lists available entry points and route types by region. Keep one stable candidate for common use cases and a backup with a different topology. When the primary route fails, switch to a backup in the same region first. If the region still has problems, change the topology. Consider another region only when the entire target region is unavailable. This order preserves the egress location required by the service while keeping useful troubleshooting clues.

CONGESTION & LOSS

Packet loss, jitter, and peak-hour congestion

Congestion is not simply “not enough bandwidth”

When multiple connections compete for the same link, network equipment queues data that cannot be sent immediately. With a short queue, users mainly notice a small delay. As the queue keeps growing, interactive requests wait behind high-volume transfers. Once the queue overflows, data is dropped, the transport layer retransmits it, and the delay grows further. Peak-hour issues commonly reflect increased competition on shared links, but congestion can occur in the home network, local access, interconnection links, relay entries, or near the target service. Time of day alone cannot identify a faulty route.

A bandwidth test mainly shows how much data can be transferred over a period; it does not fully capture queueing delay. A route may reach high download throughput while making chat, terminal work, and page rendering noticeably sluggish because a large transfer occupies sending opportunities. Conversely, a route with a less impressive peak may maintain more stable interactive response. To assess peak-hour performance, watch first-page load, sustained playback, meeting audio, terminal feedback, and connection recovery rather than relying on one speed result.

Different transport strategies respond differently to packet loss

When reliable transport encounters packet loss, it must confirm the missing data and send it again. If the missing segment is critical, later data that has already arrived may wait for it, causing a brief pause in the app. Protocols designed for fluctuating paths use different acknowledgment, retransmission, and congestion strategies to reduce overall pauses in lossy conditions, but they remain limited by the real capacity of the link. If a path is persistently overloaded, every protocol must either reduce its sending rate or accept more loss. No setting can bypass physical capacity.

The effects of light random loss and consecutive burst loss are also different. Random losses may be hidden by fast recovery, while consecutive losses are more likely to pause a session or trigger a reconnect. Wireless interference, handoffs between access points, and changing mobile signals are more likely to cause bursts. Congestion on public regional paths may appear as sustained jitter and repeated retransmissions. Improve local access first in the former case; compare relayed or dedicated topologies in the latter.

Resolve local queueing before judging the remote route

In home and office networks, upload tasks are especially likely to queue interactive requests. Cloud synchronization, photo backups, large-file uploads, and system updates can consume upstream capacity, slowing acknowledgments and requests across all connections. Switching the remote route may briefly change the queue, but the root cause remains local. Pause background transfers, try a wired connection or move closer to the access point, then compare again. When possible, managing queues and device priorities on the router is more direct than continually changing client protocols.

Wireless networks are also affected by channel contention, distance, obstructions, and nearby devices on the same frequency. If local connections pause occasionally, use another access method for comparison, such as switching from Wi-Fi to wired access or comparing networks while keeping the device still. If the issue clearly disappears after changing local access, fix the first-leg environment first. The protocol and route come later in the chain and cannot repair retransmissions that have already occurred between the device and access point.

Focus on sustained consistency during peak hours

To judge whether a route suits peak-hour use, observe it continuously during the actual usage window while keeping the target region and app fixed. Do not compare different times, websites, and local networks directly. For web services and AI Tools, watch whether requests return continuously and long conversations remain active. For streaming, watch how often buffering occurs and how smoothly playback recovers. For meetings, focus on broken audio and session rebuilds. For development work, monitor terminal sessions, code completion, and API requests over time.

If a direct route works during quieter hours but fluctuates at peak time, while a relay or dedicated route in the same region remains stable, the more controllable first-leg or regional path is valuable. If every topology fails at once, return to the local network and target service. VPNGY’s route selection is about giving each use case replaceable paths, not asking users to chase the fastest single result. For a simpler guide to choosing by region, read How to choose a VPN route, which explains the relationship between regions, route types, and use cases.

MOBILE DEVICES

Mobile battery use, network changes, and recovery

Battery drain mainly comes from sustained wake-ups and repeated reconnects

A mobile device’s network module does not consume power at one constant rate. Apps that continually send small amounts of data, clients that send frequent keep-alives, and connections that repeatedly fail and retry can all prevent the device from entering a lower-power state. Protocol computation does use resources, but in real-world scenarios, sustained wake-ups and weak wireless signals often deserve more attention. If a device repeatedly changes networks at the edge of coverage, it may consume noticeably more power through scanning, reconnecting, and rebuilding sessions even without heavy traffic.

For optimization, first disable unnecessary detailed logging and automatic tests, and avoid keeping multiple network tools active in the background. Routing rules should let local services that do not need international routes connect directly as intended, reducing the session maintenance caused by sending every request to a remote endpoint. Apps that need persistent notifications or instant messages also need the client to remain available in the background; otherwise every wake-up requires a new connection. Battery life and background availability require balance, and simply disabling background access is not a complete solution.

System power management changes client behavior

Both iOS and Android schedule background apps, but the way each client adapts and the way the system determines activity can affect connection persistence after the screen locks. Some devices pause network tasks for inactive apps and need to restore the tunnel when the screen wakes; some systems impose stricter limits on long-running background services. If the foreground works but the first request fails after the screen has been locked for a while, focus on background permissions, battery policies, and client recovery rather than immediately assuming the remote route has gone down.

For testing, keep the same route and compare foreground use, recovery after a short screen lock, switching from Wi-Fi to a mobile network, and switching back to Wi-Fi. If only screen-lock recovery fails, address background permissions. If only network switching fails, examine transport migration and client reconnect behavior. If the foreground is also unstable, check the local signal and route. These tests need no special tools, but they separate mobile-specific issues from general route problems.

Network changes test session recovery

When switching from Wi-Fi to a mobile network, the local address and egress environment change, so the existing session may become invalid. Some transports attempt migration or rapid rebuilding; others require a full reconnection. The user mainly notices whether the current request is interrupted, whether the client recovers automatically, and whether the app must reload. Hysteria2 and TUIC are generally designed with fluctuating networks and session recovery in mind, but their effectiveness still depends on client implementation and local network support.

For commuting, hotspot sharing, and mobile work, prioritize observing real recovery after a network change instead of comparing only on a fixed Wi-Fi connection. A protocol that is fast on a stable network but remains stuck in an old session after switching may not suit mobile use. A setup with ordinary peak speed but automatic recovery may be easier to live with. Keeping a basic protocol as a backup is also valuable: when a specific transport behaves badly on one access network, you can quickly determine whether the issue is the network’s support for that transport.

Troubleshooting starts in different places on different platforms

VPNGY supports Windows / macOS / iOS / Android / Linux and allows unlimited devices online at the same time. In a multi-device setup, avoid giving every device different rules and egress locations; otherwise differences become harder to identify as the same account or service moves between devices. Build stable combinations by purpose: keep a fixed region and stable route on work devices, prioritize recovery on mobile devices, and prioritize sustained transfer on media devices. Get clients through the user panel only; do not use installers or subscription URLs from unknown sources.

SCENARIO SELECTION

Choose combinations by use case

Web browsing and everyday work: prioritize low latency and clear rules

Everyday web use involves many short requests. Login, search, images, and scripts may come from different domains. A suitable combination should establish or reuse sessions quickly and ensure related domains use the intended egress location. Mature combinations such as Shadowsocks, Trojan, and VLESS can all work here. In practice, route distance, DNS resolution, and rule completeness often matter more. If the main page works but some resources fail, check domain routing first rather than replacing the entire protocol because one image did not load.

Remote work also includes document collaboration, enterprise login, and meetings. Enterprise systems may be sensitive to the egress region, so keep the region fixed and avoid frequent switching. Meetings care more about jitter and sustained sessions; compare relayed or dedicated routes within the same region first. Cloud synchronization during work can amplify local queueing, so separate interactive tasks from large transfers. Once a stable combination is confirmed, save it as a preferred entry and replace it only when a repeatable problem appears.

AI and development tools: long-lived connections and terminal environments matter more

AI conversations, code completion, and development APIs usually consist of continuous requests. Each request may not be large, but these workflows are sensitive to interruptions, DNS issues, and egress changes. The right route should maintain a stable session, and the protocol should have mature support in the current client. If a service works in the browser but fails in an editor plugin or command line, first check whether the app uses the system proxy, reads environment variables, and routes the relevant API domains through the same rule. Do not mistake differences between app network stacks for a route problem.

Development environments also deserve attention because terminals, containers, and remote environments may each have their own network settings. A working host system does not mean a container inherits the same connection. A graphical plugin being able to connect does not mean a command-line process reads the same settings. Start by confirming the host system, then move through each development layer. For connection behavior involving Cursor, Copilot, and command-line tools, read a hands-on comparison of AI coding tools. That article focuses more on development workflows; this page provides the protocol and route framework.

Streaming and large files: sustained throughput matters more than the first peak

Streaming first needs the correct egress region, then a stable, sustained transfer. A short speed test can be fast without preventing buffering throughout playback. Opening a content library also does not prove that every later media domain uses the same egress. Confirm the region first, then observe buffer recovery and quality stability during playback. A good direct path may be enough. When peak-hour fluctuations are clear, compare relayed or dedicated routes. If the local network is competing for capacity, pause background uploads first.

Large downloads can take advantage of high throughput, but they can also fill the local queue and affect other interactive tasks on the same device or network. Let download tasks use a separate route group in the client, or manage queueing on the router. Transports designed for fluctuating networks, such as Hysteria2 and TUIC, may maintain more continuous useful transfer over long distances and lossy paths, but actual stability on the current network remains the deciding factor. For more on Netflix regional libraries and bandwidth choices, see a comparison of Netflix VPN recommendations and bandwidth tests.

Public networks and privacy: confirm the connection is complete first

Public networks may involve shared congestion, captive portals, and unstable wireless coverage. Before connecting, confirm that the network itself can access the internet, then start the client. If the captive portal is incomplete, the protocol handshake may fail repeatedly. After connecting, check that target sites load fully, that system resolution follows the client’s expected path, and that multiple network-control tools are not enabled at once. Banking-grade encryption protects data in transit, but account security still depends on your own password management, device updates, and server-side login protections.

Privacy should not be judged by protocol name alone. Registration details, payment records, client permissions, DNS paths, and service logging policies together form the full picture. VPNGY requires no email address for registration; a username and password are enough. Payments support Alipay / WeChat Pay / USDT. Use a unique password, and avoid placing subscription URLs in public repositories, screenshots, or shared documents. For a more systematic review, see the privacy-first verification checklist.

Choose data and plans for real usage

Protocols and routes affect the experience, but plan selection mainly depends on actual data usage. VPNGY monthly subscriptions are ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB. Data resets monthly on the activation date, and mid-cycle upgrades are prorated by the remaining days. Data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB; they last until used and never expire. Compare all options on the plans page, which also offers a 14-day no-questions-asked refund. Do not substitute a short speed test for long-term usage planning; choose according to the share of video, downloads, development, and everyday browsing.

DIAGNOSIS

A troubleshooting process from symptoms to causes

Cannot connect at all: start with local conditions

When every route and app fails, first confirm that the local network can reach basic services. Then check whether the client has a valid subscription, the system clock is correct, and the system proxy or virtual network interface is enabled. If you just refreshed the subscription, make sure the route list has actually updated instead of continuing to use an expired cache. When multiple clients are running, fully exit the others to prevent conflicts between ports, system proxies, and routing tables. Compare different protocol entries only after local conditions are confirmed.

If a basic protocol connects but one specific protocol always fails, the issue is more likely in the client core, transport support, or subscription-field matching. Restore the defaults supplied by the service instead of manually copying selected parameters. If the same protocol works on another local network, consider whether the current network supports that transport properly. Troubleshooting notes should include the device platform, client mode, target region, route type, and failure stage. Do not write only “cannot connect,” or the issue will be difficult to locate.

Only one website is affected: check rules, resolution, and egress

If one website fails while other services work, the overall connection is usually already established. Check whether the site’s main domain, login domain, API domain, and static assets are assigned to a consistent rule group. Clearing old browser connection state or using a clean window can rule out cache and extension effects. If the site works on another device, compare the devices’ rules, DNS settings, and egress regions instead of comparing protocol names directly.

If the home page works but login or submission fails, API requests may be taking a different path, or the session may have become invalid after an egress change. Fix the route, rebuild the session, and see whether it recovers. If the target service requires a specific region, switch entry points within that region rather than trying regions at random. If the browser works but a standalone app fails, check the app’s proxy. If the standalone app works but the browser fails, check browser extensions and secure-DNS settings. Comparing apps helps determine quickly whether the issue lies outside the system proxy.

Connected but buffering often: separate local contention from remote congestion

When sustained transfer behaves badly, pause uploads, synchronization, and downloads on the same network. Move closer to the wireless access point or use a wired connection, then see whether the issue remains. If the problem clears after local conditions improve, address local queueing and wireless coverage first. If it appears only at certain times and direct routes in the same region fluctuate while relayed or dedicated routes work, make the more controllable topology your preferred option. If every route has trouble with the same target service while other services work, consider load on the target service itself.

Do not run large numbers of automatic speed tests back to back and switch routes based on them. The tests themselves create queues and may affect meetings, conversations, or playback already in progress. A more reliable approach is to use a real task for a while and observe whether the connection drops, buffering recovers, or interactive traffic is slowed by a large transfer. Compare protocols on the same route and routes with the same protocol, keeping one variable at a time.

Intermittent mobile connections: focus on system scheduling and network changes

If the mobile foreground works but the screen lock causes failures, check background permissions and power-saving policies. If Wi-Fi works but the mobile network does not, compare how each access network supports the transport. If the connection pauses after a network change, check whether the client rebuilds the session. Keep the route unchanged during these comparisons so you can identify whether the issue is in the system, access network, or remote entry. If the system stops the client, adding more remote routes will not improve recovery.

When the device becomes warm or battery use rises noticeably, check for long-term detailed logging, automatic tests, or repeated retries. Disable nonessential features and observe again. If a protocol remains unstable with the core on the current device, choose a basic protocol with more mature implementation instead of copying complex parameters. Stable operation matters more than an advanced-looking configuration.

Create a record that can be submitted and reproduced

If troubleshooting does not resolve the issue, record the device platform, local network type, client mode, target region, route type, protocol name, affected app, and exact stage. State whether the connection cannot be established, drops after connecting, affects only a specific service, or fails to recover after a network change. You may attach client error information after removing usernames, subscription URLs, and browsing content. Do not submit real passwords, payment credentials, or complete subscription links.
