What should you do if v2rayNG won’t connect? This guide walks you through troubleshooting in this order: phone network, VPN permissions, node subscriptions, routing, and DNS. It covers issues such as startup failures, timed-out tests, and being unable to open webpages despite showing as connected. Don’t repeatedly uninstall the app or sign out of your website account. Most connection issues are unrelated to your login status, and checking each item in turn makes it easier to find the cause.
1. Check your phone’s network and VPN permissions
- Stop v2rayNG and try opening a website you can normally access directly. If that doesn’t work either, first check for Wi-Fi sign-in requirements, unpaid mobile data charges, or a weak signal. Then compare Wi-Fi with mobile data.
- Turn off other VPNs, network accelerators, and ad blockers that use Android’s local VPN mode. Android generally can’t run two VPN services at once, so background conflicts may cause the connection to drop as soon as it starts.
- Tap Connect again and allow the VPN connection request from the system. If no prompt appears and the connection fails to start, search for “VPN” in system settings and check whether another app has enabled “Always-on VPN” or is blocking connections that don’t use a VPN.
- Enable automatic date, time, and time zone settings. An incorrect time can cause TLS certificate verification to fail. Don’t bypass the error by disabling certificate verification.
The VPN icon in the notification bar only means the tunnel has started; it doesn’t guarantee that the node is working. Continue checking whether you can actually access websites.
2. Check that the node and subscription are valid
Make sure you’ve selected the node you want to connect to in the list, rather than simply importing it. Update the relevant subscription in subscription management and check for errors. Even a successful update doesn’t mean every node in it is online. Free nodes may go offline temporarily, so try another recently updated node to compare.
- When importing by scanning a QR code or pasting a link, make sure the link is complete and doesn’t include extra spaces, line breaks, or explanatory text.
- If you see “Unsupported” or a parsing error, check whether the client supports the link format and transport method. Get a compatible version from the project’s official release page, and avoid modified versions from unknown sources.
- If only one node fails while others work, suspect an unavailable node or mismatched parameters first. There’s no need to reset your phone’s entire network.
Don’t rely on the latency figure alone to judge whether a node works. Select the node, connect, and run the in-app connection test (the name varies by version), then try opening a webpage. A test timeout may also be caused by the test server, so check actual access as well.
3. Connected but unable to open websites? Check routing and DNS
First, check the per-app proxy settings and make sure your browser hasn’t been excluded. Then temporarily switch to global proxy mode, reconnect, and try again. If global mode works but rule-based mode doesn’t, check whether the routing rules are outdated or matching incorrectly. Once verified, you can switch back to your usual mode.
If the logs show a DNS resolution failure, check whether you’ve enabled custom DNS or Android’s “Private DNS.” Note the original settings, then temporarily set Private DNS to Automatic and compare the results using the client’s default DNS settings. Change only one setting at a time so you can identify the actual cause.
4. Check the logs instead of reinstalling blindly
Clear the old logs and try connecting once more. A timeout usually points to an unreachable link or node; “connection refused” often means the target port isn’t accepting connections; TLS or certificate errors call for checking the time, node parameters, and client compatibility. These are troubleshooting clues, not enough on their own to confirm the cause.
If the issue persists, note the client version, Android version, network type, and error keywords, then contact your node provider. Before sharing a screenshot, hide credentials such as subscription URLs and UUIDs. Free nodes on this site should be tested using the same steps and aren’t guaranteed to remain available. Back up your configuration before reinstalling to avoid losing your subscription.
