What should you do if v2rayNG won’t connect? This guide walks you through troubleshooting in order: check your local network, verify the node, review the app settings, and test another network. This can help you tell whether the issue is a failed node, an incorrect phone setting, or a restriction on your current network. Start with small, reversible changes; don’t rush to uninstall the app, reset your phone, or repeatedly change settings.
1. First, identify what isn’t connecting
Before connecting, stop v2rayNG and use your browser to open a website you can normally access directly. If it won’t load either, first check for a Wi-Fi sign-in page, insufficient mobile data, or a weak signal. Networks at hotels, schools, and similar locations may require you to complete authentication in a browser first.
If direct access works, start v2rayNG and see what happens: failure to start the service, a node test that times out, and a service that starts but can’t load webpages are different problems. The VPN icon only indicates that a local tunnel has been established; it does not guarantee that the remote node is available.
2. Work through these low-risk checks in order
- Check VPN permission and app conflicts. When prompted for the first time, allow Android’s VPN connection request. Temporarily turn off other VPNs, ad blockers that use a local VPN, and packet-capture tools, then start v2rayNG again.
- Make sure the node configuration is complete. Select the node you just imported and check that the address, port, and protocol fields are present. Don’t guess at changes to the UUID, TLS, or transport settings. Ask the provider for the complete link and import it again.
- Update the subscription and select the node again. A successful update doesn’t mean the node is working. If the subscription update fails, first check that the link hasn’t expired. Don’t post a private subscription URL in a public group to ask for help.
- Check your system date and time. Automatic settings are recommended; a noticeably incorrect time can interfere with TLS certificate validation. Don’t bypass the error by disabling certificate checks.
- Check which apps use the proxy. If only one app can’t connect, see whether per-app proxying is enabled and whether that app is excluded. If only some websites are affected, check the routing rules. Avoid changing multiple settings at once.
3. When should you try another network?
If direct access works, the configuration is from a trusted source, and several recently working nodes all fail on the same network, try a one-time comparison: disconnect, switch from Wi-Fi to mobile data, then retry using the same node and the same settings. Keep an eye on data usage, and don’t download large files during the test.
If mobile data works but the original Wi-Fi doesn’t, the problem is more likely related to that network’s sign-in requirements, access policies, or connection. This isn’t conclusive, but it is a good reason to hold off on changing the node. Contact the network administrator or use another network you’re authorized to access. Don’t try to bypass workplace security controls.
If both networks fail, test another node from a trusted source. Free nodes may be unavailable or congested. If you use a free node provided by this site, check when it was last updated; a timeout from a single node doesn’t mean the client is broken.
4. What to do if it still fails
Open the v2rayNG log and note the test time, the error keywords, and the results on both networks. A timeout usually calls for further connectivity checks; a certificate error calls for checking the time, domain, and original configuration; a resolution failure calls for checking the network and DNS settings. Avoid copying DNS addresses from unfamiliar sources.
Before asking for help, hide your server address, UUID, subscription link, and other sensitive information. Update the app through the project’s official release channel only if you’ve confirmed that your version is outdated or the installation is damaged, and back up your configuration first. Uninstalling and reinstalling, resetting network settings, or disabling certificate verification are not recommended as first steps.
