This article addresses the common question “What should I do if v2rayNG won’t connect?” Follow this checklist to troubleshoot your phone’s network, node settings, subscription updates, system permissions, and protocol compatibility step by step. It’s suitable for everyday users and doesn’t cover setting up your own server.
1. Check your login and network environment
Many connection failures aren’t caused by a faulty client, but by your current network, system permissions, or node information. Start with these basic checks to avoid repeatedly uninstalling and reinstalling the app.
- Check your phone’s network: Close v2rayNG and open a browser to visit a domestic website. Make sure your Wi-Fi or mobile data connection is working.
- Try switching networks: If you can’t connect over Wi-Fi, switch to mobile data; if mobile data fails, try another Wi-Fi network. Some campus and corporate networks restrict proxy connections.
- Check your date and time settings: Open “Date and time” on your phone and enable automatic settings. A significant time difference can cause TLS handshake failures.
- Make sure no other proxy is running: If you’re using another VPN, accelerator, or packet capture tool, close them all and leave only v2rayNG running.
2. Check that your nodes and subscription are valid
If v2rayNG opens but won’t connect, the most common causes are expired nodes, invalid addresses, or mismatched port or transport settings. Free nodes can be unreliable, so it’s a good idea to keep a few alternatives available.
- Long-press the current node and select “Test real connection” or “Test latency.” If they all time out, update your subscription or try another node.
- If you’re using the free nodes curated on this site, copy the subscription link, then select “Subscription settings” from the menu in the top-right corner of v2rayNG and add the link. Return to the main screen and update the subscription.
- When importing an individual vmess, vless, or trojan link, make sure you copy it from beginning to end without adding spaces, line breaks, or Chinese punctuation.
- If the subscription update fails, try opening the subscription link in a browser. If it won’t open, the link itself or your current network may be the problem.
3. Troubleshoot v2rayNG settings
If your nodes are working but you still can’t connect, check the client settings. Unless you’re an advanced user, avoid changing advanced parameters at random; start by restoring the usual options.
- Open v2rayNG settings and set “Routing mode” to “Bypass LAN and mainland addresses” to prevent domestic websites from going through the proxy and causing issues.
- Check that the status at the bottom says “Connected.” If the connection drops immediately after you tap Start, check whether a VPN permission prompt appears and tap Allow.
- Open “Logs” and look for errors. A timeout usually points to a network issue or an unreachable node. Errors mentioning handshake, TLS, or certificate usually indicate an incorrect time, SNI or transport settings, or an inactive node.
- Update the client: Install the latest version of v2rayNG from a trusted source. Older versions may not support newer parameters such as VLESS, Reality, or uTLS.
4. Quickly identify the type of problem
Use these checks to narrow down the cause: If only one node fails, it’s probably inactive. If all nodes fail, first check your phone’s network, VPN permissions, system time, and subscription link. If the same node works on someone else’s phone but not yours, focus on your client version and device settings.
If you still can’t connect, try deleting your current subscription and adding it again; then switch networks and update the subscription; finally, test a different set of nodes. Don’t change too many settings at once—change one thing at a time so you can identify the cause. Remember: a stable connection usually depends on the node, network environment, and client version all working properly.
