What should you do if v2rayNG won’t connect? This guide walks you through troubleshooting system permissions, your browser, DNS, and node connections, in that order. It’s suitable if the app says it’s connected but webpages won’t load, some sites fail, or node tests time out. Start with checks you can easily undo. There’s no need to reinstall right away, and changing only one setting at a time makes it easier to identify the cause.
1. Check the app and system status
- Make sure you’ve selected a node, then tap Start. The first time you use the app, allow the VPN connection request from Android. Without permission, traffic generally can’t be routed through the proxy.
- Pause other VPNs, accelerators, or filtering tools that use a local VPN mode. Android usually can’t run multiple services of this kind at the same time.
- Check your phone’s date, time, and time zone, and use the system’s automatic settings if possible. A significant time discrepancy can cause encrypted connection verification to fail.
- If the connection drops soon after starting, check whether the system is restricting v2rayNG’s background activity or battery usage. Adjust settings for this app only; there’s no need to disable security features across the entire device.
Connected status doesn’t mean the node is working. It may only indicate that the local VPN service has started. You’ll still need to test it by opening a webpage.
2. Determine whether the problem is with the browser or the proxy
First, open a website you can normally access, then test a site that requires the proxy. If the first site won’t load either, pause v2rayNG and try again to confirm that your phone’s internet connection is working. If only the second site fails, continue troubleshooting the proxy.
- Try another browser or an incognito window to rule out extensions, cached data, or an outdated page.
- If only one browser fails, check its “Secure DNS” or custom proxy settings. Note the original values, then temporarily restore the defaults.
- Check v2rayNG’s per-app proxy settings. Make sure the browser isn’t excluded and that it’s included in the list of apps to proxy.
- You can temporarily switch to global proxy mode to test. If that fixes the problem, focus on the routing rules, then restore the previous mode after testing.
There’s no need to clear all browser data right away. Trying another browser is usually quicker and less likely to sign you out of your accounts.
3. Check DNS: change only one setting at a time
If you see a domain resolution error or some websites keep loading indefinitely, check Android’s “Private DNS” and the DNS settings in the client. Menu names may vary by system and version, so try searching in Settings.
If Private DNS is set to a custom hostname, take a screenshot to save it, then switch to “Automatic” and reconnect to test. If you’ve also changed the DNS settings in the client, restore the last configuration that worked. Don’t change DNS settings in both the system and the client at the same time—otherwise, even if the problem goes away, it’ll be hard to tell what caused it.
If your browser reports a certificate error, don’t ignore the warning and proceed. First check the system time and node settings. Changing DNS won’t fix an inactive node or an unreachable server.
4. Check that your subscription and connection are working
- Update the subscription and check whether the update fails. A successful update only means the configuration was retrieved; it doesn’t guarantee that every connection will work.
- Select another node known to work, run the connection test provided by the client, then verify it in your browser. A single latency result doesn’t reflect the full browsing experience.
- Test over both Wi-Fi and mobile data, keeping data usage in mind. If the connection fails on only one network, the issue may be related to that network environment.
- Check recent errors in the log: a timeout usually calls for a connectivity check; a resolution error points to DNS; a TLS error calls for checking the system time, configuration integrity, and node status.
Save your original configuration before making changes. If you get free nodes from pages such as freevpn-x.com, check when they were last updated and which clients they support. Don’t change protocol parameters without a good reason. If you still can’t connect, contact the provider with your client version, network type, and redacted error details. Never share your subscription link, password, or full node configuration publicly.
