v2rayNG shows as connected, but your browser can’t open web pages, or node tests keep failing. Where should you start troubleshooting? This guide checks the browser, system proxy, DNS, and node routes in order. It prioritizes reversible steps so you don’t have to start by clearing your configuration, reinstalling the app, or changing a bunch of settings.
1. First determine whether the problem is with the browser or the connection
A VPN icon doesn’t mean the node is connected; it usually only indicates that Android has established a local VPN interface. Keep your current configuration, then follow the steps below to narrow down the cause.
- Stop v2rayNG and open a website that normally works without a proxy to make sure your Wi-Fi or mobile data is working. If the network requires a sign-in, complete that first.
- Reconnect, then visit one website that works without a proxy and one that you need to access through the proxy. Don’t diagnose the problem based on just one page.
- Try another browser or an incognito window. If only one browser is affected, check its secure DNS settings, extensions, and site cache first.
- Switch between Wi-Fi and mobile data. If it fails only on one network, the cause is more likely to be that network’s restrictions, DNS resolution, or route accessibility.
2. Check for VPN conflicts and routing scope
Android usually can’t run two apps that use the system VPN interface at the same time. Temporarily disable other VPNs, ad blockers that use a local VPN, or packet-capture tools, then start v2rayNG. If prompted, allow it to establish a VPN connection.
Next, check whether per-app proxying is enabled and whether your browser is excluded. For troubleshooting, you can temporarily disable per-app restrictions or add the browser to the proxy scope. Also check the routing mode: if you suspect a routing rule is incorrect, briefly switch to global proxy mode to test, then restore the original mode. Change only one setting at a time and note its original value so you can tell which change made a difference.
3. Troubleshoot DNS: restore the defaults first, then compare
If you see errors like “server not found” or “DNS resolution failed,” while some apps can still connect, check DNS. First, look at “Private DNS” in Android settings. If a custom hostname is configured, temporarily switch to Automatic and try again; the menu location varies by system. If your browser has its own secure DNS setting, you can also temporarily restore its default to compare.
Then check whether you’ve changed any DNS-related options in v2rayNG. Option names and default behavior may differ between versions, so don’t copy addresses or parameters from unfamiliar guides; first restore any settings you changed yourself. After making a change, stop and reconnect, then reopen the browser and test again. Don’t change DNS in the system, browser, and client all at once, or it will be hard to pinpoint the problem. If the test doesn’t help, restore the original settings.
4. Check that your subscription and node routes are working
Open subscription management, update the subscription manually, and check whether it succeeds. A failed update doesn’t necessarily mean all your existing nodes are down; the subscription URL may simply be temporarily inaccessible. Don’t delete the old subscription yet. Make sure the URL is complete, contains no extra spaces, and follow the service provider’s instructions.
Select a node and run the connection or latency test provided by the client, then verify by opening a webpage. Test results are only clues and don’t guarantee that every website will work. Try another route from the same subscription for comparison. Free nodes may also stop working temporarily, so judge them by the actual connection result.
If all routes fail, check that your system date and time are set to sync automatically, and look in the logs for clues such as timeout, DNS, or TLS errors. When asking for help, include the client version, network type, and checks you’ve already done. Don’t share your subscription link, UUID, or full node QR code publicly. If you still can’t identify the cause, back up your configuration first, then check for updates through the project’s official release channel; there’s no need to rush into reinstalling.
