This guide addresses the common question, “What should I do if v2rayNG won’t connect?” Often, the node itself isn’t necessarily down—the issue may be caused by interactions between your phone’s network, DNS, routing mode, browser cache, and system proxy settings. Follow the troubleshooting steps below in order. They’re suitable for users of VLESS, VMess, Trojan, and other nodes or subscriptions.
1. Check the node and client status
After opening v2rayNG, avoid repeatedly switching between apps. First, check the basics:
- Make sure v2rayNG is updated to a recent version. Older versions may be incompatible with some Reality, TLS, or transport settings.
- Long-press the current node and select “Test current configuration (real connection)” or a similar test option. If it times out, try another node from the same subscription.
- Check that your phone’s time is set to sync automatically. A significant time discrepancy can cause TLS-based protocols to fail during the handshake.
- If you’re using free nodes provided on this site, copy the subscription or node link again and import it to avoid using an outdated configuration.
If only one node fails, it’s probably unavailable or its settings have changed. If all nodes fail, continue by checking your device’s network environment.
2. Check your IP network: try both Wi-Fi and mobile data
Many cases where the connection succeeds but webpages won’t load are related to the current IP network. First, turn off v2rayNG, switch networks, and test again:
- Switch from Wi-Fi to mobile data, or vice versa.
- Restart your router to refresh your local network connection.
- Turn off battery saver and data saver modes on your phone to prevent the system from restricting the VPN in the background.
- If your workplace, school, or hotel Wi-Fi has strict restrictions, try mobile data first to check whether the node is working.
If mobile data works but Wi-Fi doesn’t, the issue is usually with the router, your carrier’s DNS, or local network restrictions. If neither works, check DNS and app settings next.
3. Check DNS and routing mode settings
Incorrect DNS settings can allow you to connect to the proxy but prevent websites from resolving. Open v2rayNG’s settings and, if you’re an average user, start with the default DNS. If you’ve changed advanced settings, restore the defaults and restart the connection. You can also try setting “Routing” to global mode to see whether routing rules are preventing certain websites from using the proxy.
Recommended troubleshooting order: first, use global proxy mode to see whether you can open the target website. If it works, switch back to bypassing mainland China addresses or to rule-based proxy mode. This helps determine whether the problem is with the node or with a routing rule being applied incorrectly.
4. Your browser can also affect the results
Sometimes v2rayNG is connected properly, but your browser still can’t load pages. The cause may be a cache, DoH, an extension, or conflicting proxy settings. Try the following:
- Test with another browser, such as by comparing your system browser with Chrome.
- Clear your browser cache, turn off Private DNS and proxy acceleration, and disable ad-blocking extensions before trying again.
- Don’t run another VPN, network accelerator, or proxy app at the same time, as this may cause port conflicts.
- Test multiple websites rather than relying on just one to determine whether the connection is failing.
If the Telegram or YouTube app works but your browser doesn’t, focus on the browser’s DNS, cache, and extensions. If no apps work, return to troubleshooting the node and network.
5. Quick troubleshooting checklist
If v2rayNG won’t connect, try these steps in order: update the client → import the subscription again → switch nodes → switch between Wi-Fi and mobile data → restore the default DNS settings → test in global mode → try another browser. Most problems can be traced to one of these steps. If it still fails, note the error message, node protocol, and network type before searching for a solution. This will make troubleshooting much more efficient.
