What should you do if v2rayNG won’t connect? This article walks you through troubleshooting in the following order: check your network, confirm permissions, update your nodes, and switch networks. This can help you determine whether the issue is with your phone, a node, or your current network. The steps prioritize reversible actions, so you don’t need to uninstall the app, clear your configuration, or reset your phone’s network settings right away.
1. First, identify the type of connection failure
First, stop the v2rayNG connection, then use your browser to open a domestic website that normally works. If you still can’t access the internet with the proxy turned off, first check for Wi-Fi login requirements, unpaid mobile data charges, or a weak signal. Test the proxy again once your basic network connection is restored.
If the app shows that it’s connected but webpages won’t open, keep in mind that the VPN icon only means your phone has established a local VPN tunnel; it doesn’t mean the node is working. A node test timing out doesn’t, on its own, prove that the node is down. Check actual access and the logs as well.
2. Perform these low-risk checks in order
- Check VPN permissions and conflicts: When you tap Start, allow the VPN connection request from Android. Temporarily turn off other VPNs, accelerators, or filtering tools that use a local VPN to prevent them from competing for the system’s VPN connection.
- Confirm which node is selected: Check that the node you want to use is actually selected in the list. If you imported the configuration from a subscription, update it once in subscription management. If the update fails, keep the existing configuration; don’t delete the entire subscription.
- Check that the import is complete: If you copied the link manually, make sure it wasn’t cut off, padded with spaces, or missing parameters. Prefer copying and importing the complete link again, and don’t change the address, port, transport protocol, or TLS options at random.
- Check the system time: In your phone’s settings, enable automatic date and time. A significantly incorrect time can cause certificate verification to fail. After correcting it, stop the connection and start it again.
- Test another node: Note the original node, then test another node from the same subscription. You can also use a free node from this site for comparison, but free nodes may not always be available, so don’t assume that a single node failure means the app is faulty.
3. When should you switch network environments?
If your network works with the proxy turned off, and you’ve confirmed the permissions and configuration, but multiple nodes still won’t connect, try a comparison test on Wi-Fi and mobile data. Stop the connection, turn off Wi-Fi, confirm that your phone is using mobile data, then start the same node and open the same webpage. The test will use mobile data, so remember to switch back when you’re done.
If the same node works on mobile data but not on a particular Wi-Fi network, the issue is more likely related to that Wi-Fi network’s authentication, access policies, or network route. Complete any login steps for public Wi-Fi first. Follow your organization’s rules on workplace or school networks; don’t disable security software or install unfamiliar certificates just to test the connection.
If both networks fail, first check whether the node has expired, the subscription is still valid, or the app needs an update, rather than repeatedly switching networks. The comparison results are only clues for troubleshooting and don’t prove that your carrier is imposing restrictions.
4. If it still fails, check the logs before asking for help
Menu names may vary between versions, so look for the logs section in the app. For timeout errors, check both the network and the node. If domain name resolution fails, check whether the system’s Private DNS is set to an unavailable custom service. For certificate errors, first verify the time and configuration; don’t simply bypass certificate verification.
When asking for help, include your Android and app versions, what happens when the connection fails, the results of testing both networks, and redacted logs. Don’t share complete subscription links or node credentials publicly. Until you know the cause, keep the original configuration and change one thing at a time so you can easily undo each change.
