What should you do if v2rayNG won’t connect? This guide troubleshoots issues in the order of network conditions, system permissions, node subscriptions, routing, and DNS to help resolve problems such as no internet access after startup, node timeouts, and some websites not loading. Don’t rush to reinstall the app. Change one thing at a time and test so it’s easier to identify the cause.
1. Check your network and phone environment
- Close v2rayNG and try opening a regular website in your country. If that doesn’t work either, first check your Wi-Fi or mobile data connection, or whether your service has been suspended for nonpayment. Public Wi-Fi may require you to sign in through a browser first.
- Switch between Wi-Fi and mobile data once. If the problem occurs on only one network, suspect restrictions on that network before assuming the node has failed.
- Go to your system’s date and time settings and enable automatic time synchronization. A significantly incorrect time can interfere with TLS certificate verification.
- Turn off other VPNs, proxies, and filtering tools that use the VPN connection. Android generally can’t run multiple standard VPN connections at the same time.
A “started” status in the app doesn’t mean the node is connected. The VPN icon in the status bar only indicates that the system tunnel has been established. Verify the connection by actually opening a website.
2. Make sure permissions and background activity aren’t blocked
When you start v2rayNG, allow the system’s VPN connection request. If the app stops immediately after you tap Start, check whether you denied permission by mistake and whether another app has “Always-on VPN” enabled or an option that blocks connections without a VPN. Menu locations vary between phones.
If the connection works at first but drops when the screen locks, allow the app to run in the background in its battery settings, and check power-saving mode and background data restrictions. Only exempt apps that need it; there’s no need to disable all security settings. Get the client from the project’s official release channels whenever possible, and avoid modified versions from unknown sources.
3. Check that the node is complete and the subscription hasn’t expired
- Make sure you’ve selected the target node in the list, rather than simply importing a subscription. Stop the service, select the node again, then restart and test.
- Use the subscription manager’s update function and check whether the update succeeds. A failed update doesn’t necessarily mean the existing nodes are no longer working; the subscription URL may simply be temporarily unreachable.
- Copy the node link again from its original source or scan the QR code. Check for missing characters, spaces, or text truncated by a messaging app. Don’t guess at changes to the port, UUID, transport method, or TLS settings.
- Test with another node from a trusted source that was updated recently. Free nodes provided by this site should also be judged by the results of each connection attempt; their availability isn’t guaranteed.
Latency numbers aren’t the final measure of success. Test results in the list may differ from what you experience when browsing. Select a node, start the service, and then open a website to verify. Don’t submit subscription URLs to unfamiliar online testing sites, as they may contain access credentials.
4. Tell routing and DNS issues apart from node failures
If domestic websites work but some international sites don’t, check whether your routing rules are appropriate. You can temporarily switch to a mode that proxies all traffic for comparison; the exact name depends on the client version. After testing, switch back to rules that suit your everyday use.
If the logs report a domain name resolution failure, check the client’s DNS settings and Android’s “Private DNS” setting. If you’ve entered a custom address, note it down, then try restoring the default or automatic setting. Don’t change DNS, routing, and node settings all at once, or it will be difficult to tell which change helped.
Check the client logs. A timeout usually warrants checking the network or whether the node is reachable. For a certificate error, verify the time, node domain, and configuration source. A connection refusal may mean the destination port or service is unavailable. Don’t disable certificate verification to hide an error.
5. What to include when asking for help
Note your phone’s OS version, v2rayNG version, network type, what happens when the connection fails, and any relevant logs. Also mention the results of testing with a different network or node. Before sharing screenshots, hide credentials such as subscription URLs and UUIDs. Following the steps above should usually help narrow the cause down to the local environment, node configuration, or network restrictions so you can address it more effectively.
