This article addresses the common question, “What should I do if v2rayNG won’t connect?” If your imported node times out, you can’t access the internet, the TLS handshake fails, or connection tests keep failing, work through the checklist below. Start by ruling out issues with your phone, node details, proxy mode, and network restrictions.
1. Check your phone and network environment
Many connection failures aren’t caused by the node itself. They’re often due to incorrect system time, missing network permissions, or restrictions on your current Wi-Fi network. Start with these basic checks before repeatedly uninstalling and reinstalling the app.
- Make sure your system time is correct: Go to “Date & time” on your phone and enable automatic time setting. An incorrect time can cause connection verification to fail for TLS, Reality, and other protocols.
- Try a different network: If you can’t connect over Wi-Fi, switch to mobile data. If mobile data doesn’t work, try another Wi-Fi network. Some school or workplace networks restrict proxy connections.
- Turn off other VPNs: Android usually allows only one VPN service to run at a time. First disable any accelerators, VPN-based ad blockers, or other proxy apps.
- Check v2rayNG permissions: Allow the app to run in the background and use mobile data. Some devices also require you to disable battery-saving restrictions.
2. Check that the node was imported correctly
If your environment is working properly, check the node details next. v2rayNG supports protocols such as VLESS, VMess, and Trojan. An error in any field during import can prevent the connection from working.
- Subscription users: Open v2rayNG, tap the menu in the upper-right corner, and select “Subscription settings.” Make sure the subscription link is complete, then tap “Update subscription.”
- Manual import users: Check that the address, port, UUID, encryption method, transport protocol, SNI, path, host, and other fields are present and correct.
- QR code import users: If the QR code is blurry or the copied content is incomplete, copy the share link again and import it.
- Users of this site’s free nodes: Nodes may stop working due to network fluctuations. If one fails, try other nodes on the same page instead of repeatedly testing just one.
3. Check these settings in v2rayNG
Open v2rayNG, select a node, and tap the circular button in the lower-right corner to connect. If a key icon appears at the top of the screen, your phone’s VPN is running, but that doesn’t necessarily mean the node is working. Long-press the node and select “Test current service connection” for a more useful result than a simple latency test.
For proxy mode, most users should start by testing “Bypass LAN and mainland addresses” or “Global proxy.” If global proxy works but bypass mode doesn’t, the issue may be with the routing rules. If global proxy doesn’t work either, the node or network environment is more likely the cause. If your browser can open domestic sites but not overseas sites, make sure v2rayNG is connected, then try clearing your browser’s DNS cache or using a different browser.
4. How to fix common errors
- timeout / i/o timeout: Usually means the node is unreachable, the port is blocked, or the current network is restricting connections. Try another network or node.
- handshake failed: Often caused by an incorrect system time, an SNI mismatch, or incorrect TLS/Reality settings.
- connection refused: The server port may be closed or the node may no longer be working. Most users can simply switch to another node.
- Subscription update failed: Check that the subscription address was copied in full. Try updating with the proxy turned off, or switch networks and try again.
In short, troubleshoot in this order: phone time and network → conflicts with other VPNs → subscription/node details → v2rayNG proxy mode → try another node. If you’ve checked everything and the problem persists, take a screenshot of the error and note the protocol type and error message. This will make it easier to diagnose the issue.
