This article addresses the common question “What should I do if v2rayNG won’t connect?” It’s intended for beginners who have just imported a node and can’t get online after tapping Connect. Follow the steps below to troubleshoot: first check your phone’s network, then check your nodes and subscription, and finally review v2rayNG settings and system permissions. This should help you identify most issues.
1. Check whether the problem is with your phone’s network
Many connection failures aren’t caused by a faulty node, but by an unstable network. Don’t immediately reinstall the app; first make sure your phone can access the internet normally.
- Close v2rayNG and use a browser to visit a domestic website, such as a search page or news site, to confirm that your regular connection works.
- Switch between Wi-Fi and mobile data to test both. Some campus, office, and public Wi-Fi networks restrict proxy connections.
- Turn off your system’s battery saver and data saver modes to prevent background network access from being restricted.
- If you’re using another VPN, accelerator, or proxy tool, disconnect them all first and use only v2rayNG.
If you can’t access domestic websites either, the problem is with your basic network connection. Check your Wi-Fi, data plan, router, or carrier network first. If domestic websites work but v2rayNG doesn’t, continue with the steps below.
2. Check whether the node is invalid or was imported incorrectly
v2rayNG relies on node details to connect. Expired nodes, blocked addresses, incorrect ports, and incorrect UUIDs can all prevent a connection. This site compiles free nodes for testing, but their stability depends on the number of users and network conditions, so it’s a good idea to keep several backup nodes available.
- Long-press the current node and select “Test connection” or “Test real connection” to see if it returns a result.
- Try a node in a different region or using a different protocol. Don’t keep retrying the same node.
- If you’re using a subscription, open the subscription settings and tap Update subscription. Make sure no download error appears.
- When importing a share link, make sure you copy the full link, including the prefix, such as vmess://, vless://, or trojan://.
If all nodes fail, first suspect that the subscription URL is unavailable, the network is blocking the connection, or the client is misconfigured. If only one node fails, it’s most likely no longer working.
3. Check v2rayNG’s basic settings
Common beginner mistakes include changing the routing mode, proxy mode, or permissions. Start by restoring the app to a simple, working configuration.
- Open v2rayNG, select a node, and tap the connect button in the lower-right corner. Confirm that a key icon appears in the status bar.
- Open Settings and set the routing mode to “Bypass LAN and mainland China addresses” or use the default rules. Avoid importing complex rules without a specific need.
- If prompted for VPN permission, tap Allow. If you previously denied permission, you may need to grant it again in your system settings.
- Check that your phone’s date and time are correct. A significant time discrepancy can cause TLS-related connection issues.
Some phone systems also terminate background apps. In your app management settings, allow v2rayNG to run in the background and disable battery optimization for it.
4. Use the logs to identify the specific error
If you still can’t connect, open the v2rayNG logs. You don’t need to understand every entry, but a few keywords can be helpful: timeout usually means the network is unreachable or the node isn’t responding; connection refused may mean the port is unavailable; failed to resolve is often related to DNS or network name resolution; TLS- or certificate-related errors may indicate a node configuration or time issue.
When troubleshooting, try these steps in order: switch networks, switch nodes, update the subscription, restart the client, and check the logs. Avoid frequently changing advanced settings you don’t understand, or you may make a simple problem more complicated.
5. Quick troubleshooting checklist
- Can you access domestic websites? If not, fix your basic network connection first.
- Have you tried both Wi-Fi and mobile data?
- Did the subscription update successfully? Have you tested the nodes?
- Does v2rayNG have VPN permission?
- Are your phone’s time, background permissions, and battery optimization settings correct?
In short, if v2rayNG won’t connect, don’t rush to uninstall it. Troubleshoot your network, node status, client settings, and logs in that order, and you can usually find the cause. If you use free nodes, keep several from different sources and update your subscription regularly to reduce the impact of nodes becoming temporarily unavailable.
