What should you do if v2rayNG won’t connect? This guide walks you through troubleshooting in order: browser, system permissions, DNS, and node routes. It helps you tell the difference between “the client isn’t routing traffic” and “the node itself is unavailable.” The steps prioritize reversible changes, so there’s no need to reset your phone’s network settings, and you shouldn’t uninstall the app as a first step.
1. Check the connection status and your basic network
First, stop v2rayNG and check whether you can access your usual websites over your current Wi-Fi or mobile network. If the basic connection is also having problems, complete any Wi-Fi sign-in first or try a different network. Don’t change node settings yet.
- Open v2rayNG, select a node, and tap the start button. The first time you connect, allow Android to create a VPN connection.
- Check whether the VPN icon appears in the system status bar. It only indicates that the tunnel has been established; it does not mean the node can necessarily access the internet.
- Pause any other VPNs, proxies, or network-filtering tools that might be occupying the system VPN slot. Keep your original settings and restore them after testing.
- Run a connection test from the client menu. The option may have a different name in other versions. A timeout is only a clue; don’t conclude that a node is unavailable based on a single test.
2. If only your browser won’t load pages, check the browser first
If other apps work and only one browser can’t open webpages, try visiting the same URL in another browser, then test it in a private window. A private window won’t bypass the proxy, but it can help you determine whether cookies, cache, or extensions are interfering.
Check v2rayNG’s per-app proxy settings and make sure the browser hasn’t been excluded. If you’re using rule-based routing, you can temporarily switch to global proxy mode for comparison, then restore the original mode after testing. If global mode works but rule-based mode doesn’t, check the routing rules rather than immediately replacing all your nodes.
If your browser has custom “Secure DNS” enabled, note the current setting, then temporarily switch to the system default for testing. Don’t disable HTTPS certificate verification to troubleshoot connection problems, and don’t install unfamiliar certificates prompted by a webpage.
3. If you suspect DNS, change one setting at a time
If you see errors such as “DNS address could not be found” or “server not found,” focus on DNS. Android’s “Private DNS,” your browser’s Secure DNS, and the client’s DNS settings may all affect name resolution. The exact behavior depends on the app version and proxy mode.
- Take screenshots of your current settings first so you can restore them if needed.
- If you’ve entered a custom hostname for Private DNS, temporarily change it to “Automatic,” reconnect, and test again.
- If you’ve manually changed DNS in the client, check the instructions for your version and restore the defaults first. Don’t copy unfamiliar configurations.
- After each change, reconnect and visit the same website. If it doesn’t help, restore the setting before checking the next one.
4. Finally, check whether the node and route are available
First, check your phone’s date and time. Automatic settings are recommended, since a significantly incorrect time can interfere with TLS verification. Then update your existing subscription and check for errors. A successful subscription update doesn’t mean all the nodes it contains are available; select an updated node and test it directly.
Try another node, then test over both Wi-Fi and mobile data. If only one node fails, it’s likely unavailable. If the same node fails only on one type of network, the issue may be related to the network environment or route. Free nodes on this site should also be tested individually; their availability isn’t guaranteed.
If you still can’t connect, check the client logs for DNS resolution failures, connection timeouts, or TLS errors, and note the app version, network type, and test results. Before asking for help, hide your subscription link, UUID, and password, and don’t share your full configuration. Don’t try to mask errors by disabling certificate verification.
