This article explains what to do when v2rayNG won’t connect. It’s designed for beginners to follow step by step, from checking the phone’s network and node details to updating subscriptions and reviewing client settings, so you can determine whether the problem is your local network, an unavailable node, or an import error.
1. First, check that your phone’s network is working
Many connection failures aren’t caused by v2rayNG itself but by an unstable network. First, close v2rayNG and use your browser to visit a domestic website, such as a search page, video site, or app store. If those websites won’t load either, you’ll need to troubleshoot your phone’s network first.
- Switch between Wi-Fi and mobile data, and test each connection.
- Turn off Airplane mode, data limits, and battery saver mode to prevent the system from restricting background network access.
- If you’re using company, school, or hotel Wi-Fi, try mobile data instead, as some public networks restrict proxy connections.
- Restart your router or phone, then open v2rayNG and test again.
If your domestic network works but v2rayNG still shows a connection failure, continue by checking your nodes and configuration.
2. Check whether the node is available
v2rayNG requires an imported node, such as V2Ray, VLESS, VMess, or Trojan, to connect. Free nodes may stop working because of high traffic, routing changes, or blocking, so don’t test just one node.
- On the v2rayNG home screen, long-press a node and select “Test current configuration’s real connection” or “Test all configurations.”
- If the latency shows -1, timeout, or all tests fail, try a different node first.
- If only some nodes work, the client is likely functioning normally and the nodes simply have different statuses.
- When copying nodes from this site or another source, make sure the full link is included, such as vmess://, vless://, or trojan://.
We recommend importing several nodes and testing them one by one, then choosing a line that connects successfully and has low latency. Don’t tap Connect repeatedly; after switching nodes, wait 5–10 seconds before checking the result.
3. Recheck subscription import and updates
If you use a subscription link, first make sure it imported successfully. Open the menu in the upper-right corner of v2rayNG and select “Subscription settings.” Check that the link is complete and contains no extra spaces or line breaks, then tap “Update subscription.”
If the update fails, try opening the subscription link in your phone’s browser. If it won’t open there either, the subscription URL may be invalid, the network may be unable to reach it, or the link may have been copied incorrectly. If it opens in the browser but v2rayNG can’t update it, try deleting the old subscription and adding it again.
When importing a single node manually, make sure the protocol type and all parameters are correct and complete. A blurry QR code, incomplete copy, or a link truncated by a messaging app can all cause connection failures.
4. Check v2rayNG client settings
Once you’ve confirmed the node is available, check the client’s basic settings. Beginners usually don’t need to change many parameters; changing settings at random can make things worse.
- Make sure you’ve tapped the circular button in the bottom-right corner to start the proxy and that the VPN icon appears at the top of your phone’s screen.
- In Settings, try selecting “Bypass LAN and mainland addresses” for the routing mode, or use the default rules.
- If per-app proxying is enabled, make sure apps such as your browser, Telegram, and YouTube aren’t excluded.
- If you’re having issues with “Proxy only” mode or related settings, try turning them off and restoring the defaults.
If the VPN icon appears but webpages won’t load, check the v2rayNG logs for errors. A timeout usually indicates a node or network problem; “failed to connect” or “connection refused” may mean the node is unavailable; TLS, certificate, or UUID errors usually indicate an incomplete configuration or mismatched parameters.
5. Quick troubleshooting steps if it still won’t connect
Try these steps in order: update v2rayNG to the latest version; delete unavailable nodes; import the subscription again; switch between Wi-Fi and mobile data; restart your phone; then test multiple nodes. Don’t change several settings at once, or it will be difficult to tell which change caused the problem.
In summary, if v2rayNG won’t connect, first rule out local network issues, then confirm that the node is available, and finally check the subscription and client settings. This site provides free nodes and import guides, but free connections can be unstable, so it’s best to keep several backup nodes ready in case one fails.
