This article addresses the following problem: v2rayNG suddenly stops connecting on a phone. In particular, when several people on a team share a subscription or node, how can you tell whether the cause is client settings, account restrictions, the network environment, or an unstable node? It also provides troubleshooting steps you can follow.
1. First, check whether “no one can connect”
When your team uses v2rayNG, don’t immediately reinstall it over and over. First narrow down the scope: if only one phone can’t connect, the issue is more likely to be that device’s network, time, DNS, or configuration. If multiple team members are failing at the same time, focus on the subscription, account status, and node availability. The same approach applies when testing the free nodes available on this site, as their performance can vary with the number of users and network conditions.
- Ask 2–3 team members to test on different networks, such as Wi-Fi, mobile data, and the company network.
- Switch between at least two nodes on the v2rayNG home screen instead of testing just one.
- Tap the menu in the top-right corner and select “Test all configurations for real connectivity” to check for latency or error messages.
- Note the time of the failure, the carrier, and the node name instead of just reporting that it “doesn’t work.”
2. Check that the subscription and account are working
Many “what should I do if v2rayNG won’t connect?” issues are actually related to account stability. When several people on a team share the same subscription, the configuration may stop working if the server limits the number of devices connected at once, the subscription link expires, or the nodes are replaced. You don’t need to know how to configure the server; just check the client.
- In v2rayNG, long-press the subscription group and select Update subscription. Check that there’s no download error.
- If you imported the link by pasting it, make sure it’s complete and includes a prefix such as vmess://, vless://, or trojan://.
- Make sure your phone’s date and time are set to sync automatically. An incorrect time can cause the TLS handshake to fail for some nodes.
- Avoid sharing the same account across too many devices at once, as this can trigger restrictions or cause instability.
How to tell: If the same subscription works on one phone but not another, check the phone that’s failing first. If it fails on all phones, update the subscription or try a different source for nodes.
3. Troubleshoot v2rayNG settings on the phone
If the subscription is fine, check v2rayNG on the phone. First, update the app to a recent version, then follow these steps in order:
- Close and reopen v2rayNG, tap the current node, then tap the connect button in the bottom-right corner.
- Open your phone’s system settings and make sure v2rayNG is allowed to use mobile data and Wi-Fi.
- Turn off other VPNs, network accelerators, and packet-capture tools. Only one VPN tunnel can be active at a time.
- In v2rayNG settings, toggle “Bypass LAN and mainland China addresses” and test again.
- To clear the DNS cache, turn Airplane mode on for 10 seconds, then turn it off.
Common symptoms: If the app shows that it’s connected but webpages won’t open, the issue may be DNS or routing rules. If the connection drops immediately after you tap Connect, the configuration may have expired, the port may be blocked, or the phone may have a permissions issue.
4. Tips for stable use by a team
The biggest risk for a team is that “one person changes the subscription and nobody else knows.” Assign one team member to maintain the node list, and avoid sharing multiple outdated links in the group chat. After updating the subscription, have a few people test it first, then ask everyone to update. If you use this site’s free nodes, keep 2–3 backup configurations ready so you can switch quickly if a connection fails, rather than repeatedly changing phone settings.
Bottom line: If v2rayNG won’t connect, first check how many people are affected, then check the subscription and account, and finally check the phone’s settings. When several people on a team share a subscription, simultaneous connections, expired subscriptions, and differences in network conditions can all affect stability. Recording and comparing the results at each step will usually help you pinpoint the issue quickly.
