This article addresses the following problem: when multiple people on a team use v2rayNG, some can connect while others fail. How do you determine whether the cause is client settings, node subscription, network environment, or account/environment stability? The checks below are ordered by what ordinary users can do first and do not involve self-hosted server configuration.
1. First confirm whether it is an “individual issue” or a “team-wide issue”
The easiest mistake teams make when using v2rayNG is assuming a node is broken just because one person cannot connect. It is recommended to do cross-checking first: test the same node with 2–3 team members on different networks; on the same phone, switch between Wi-Fi and mobile data for testing. If only one member fails, it is most likely a local configuration or network environment issue; if most people fail at the same time, then focus on checking the subscription, node availability, or remote-side policies.
- Open v2rayNG, go to the node list, and confirm that the currently selected node is not an empty configuration.
- Tap the menu in the upper-right corner and select “Test all configurations with real connection” or a similar test option.
- Ask team members to report whether they can connect, what network they are using, the failure message, and the system version.
- Record the failure time consistently to avoid mistaking temporary network fluctuations for a long-term fault.
2. Check whether the subscription or nodes have expired or were imported incorrectly
Many “what to do if v2rayNG cannot connect” issues are actually caused by subscriptions not being updated. When a team shares a subscription, if someone has not refreshed it for a long time, their client may still contain old nodes and naturally be unable to connect. In v2rayNG, go to subscription settings, update the subscription first, and then reselect a node to test. If you are using the free nodes provided on this site, it is also recommended to recopy the subscription link or node content first and make sure nothing was missed, no line-break errors were introduced, and QR code recognition did not fail.
Note: Do not let multiple people repeatedly forward truncated links. It is best for one responsible person to distribute the original subscription address and remind members to update regularly. If, after importing, node names appear garbled or the number of nodes is clearly incorrect, it usually means there is a problem with the subscription format, network access, or clipboard content.
3. Check local phone settings and network permissions
When one person cannot connect, check the local environment first. Android may restrict background activity, VPN permissions, or power-saving policies, causing v2rayNG to disconnect shortly after startup. Please check whether VPN connections are allowed, whether data restrictions are disabled, whether security software is blocking it, and whether the system time is accurate. If the time differs too much, some protocol handshakes may fail.
- Restart v2rayNG, then remove the old authorization in the system VPN settings and grant permission again.
- Turn off other proxies, accelerators, and packet-capture tools to avoid port or routing conflicts.
- Switch between mobile data and Wi-Fi to test whether the issue is caused by carrier restrictions or the company network.
- In routing settings, try “Bypass LAN and mainland China addresses” or test with the default global mode.
Recommendation for team scenarios: Do not let members casually modify fields such as transport protocol, TLS, SNI, or port. Most imported nodes already include complete parameters, and manual changes often cause different results on the same node.
4. The relationship between account/environment stability and team usage
So-called account/environment stability mainly refers to the subscription source, number of users, connection frequency, and whether the network egress is consistent. If many team members use the same batch of nodes for a long time, peak-time congestion, temporary rate limits, or inaccessibility on some networks may occur. Free nodes are especially affected by the number of online users and line status, making them suitable only as temporary backups and not for long-term stability guarantees.
A more reliable approach is to establish simple team rules, such as updating subscriptions at a fixed time every day; when a fault occurs, switch nodes first, then switch networks; provide error screenshots in a consistent format; and avoid frequent bulk speed tests, which may create additional load. For teams that need long-term use for work, it is recommended to prepare multiple subscription sources or backup clients such as Clash and sing-box for easier cross-checking.
5. How to handle common error messages
If the message says timeout, it is usually because the network is unreachable or the node is congested, so switch networks or nodes first; if it says connection refused, the node port may be unavailable; if it always shows connected but web pages will not open, check the routing mode, DNS, or leftover browser proxy settings. Finally, you can try clearing the v2rayNG app cache and reimporting the subscription.
Summary: When a team is troubleshooting v2rayNG connection failures, the key is to first distinguish between an individual issue and a shared issue, then check layer by layer: subscription, node, local permissions, and network environment. Do not start by changing advanced parameters; use cross-testing and unified feedback first, and you can usually identify the cause more quickly.
