This article addresses the common issue of “What should I do if v2rayNG won’t connect?”: when you can’t access the internet after importing nodes, testing keeps failing, or you have no internet after connecting, you can troubleshoot in a low-risk order. Avoid changing complex settings at the start, so things don’t get more and more confusing.
1. First, confirm whether it’s a basic configuration issue
A v2rayNG connection failure does not necessarily mean the node has expired. In many cases, it is caused by switches, time settings, proxy mode, or an outdated subscription. It is recommended to check in the following order:
- Open v2rayNG, make sure a node is selected, and tap the button in the lower right corner to start the proxy.
- Pull down the notification panel and confirm that the VPN icon appears; if not, the local proxy has not actually started.
- Go to your phone’s “Date & time” settings and enable automatic time and automatic time zone. Incorrect time may cause TLS connection failures.
- In v2rayNG, tap the menu in the upper right corner and choose “Test all configurations with real connection” or test the current node.
- If you use a subscription, update the subscription first; for the free nodes on this site, it is also recommended to update before testing to avoid using expired configurations.
If only one specific node fails while others work normally, that node is usually unavailable. If all of them fail, continue checking the network environment.
2. When you need to switch network environments
The principle of low-risk troubleshooting is: switch networks first, rather than randomly changing protocol parameters. In the following situations, you can consider switching network environments:
- All nodes in the same batch fail on your home Wi-Fi, but some work after switching to mobile data.
- v2rayNG shows errors such as timeout, handshake failed, or connection reset.
- You cannot connect on company, campus, or hotel Wi-Fi, but it works again after switching to a personal hotspot.
- Your browser and other apps can access the internet, but v2rayNG real-connection tests keep failing.
It is recommended to try in this order: “current Wi-Fi → mobile data → another Wi-Fi → personal hotspot.” This will not disrupt your existing configuration and also makes it easier to determine whether the issue is with the node or network restrictions on the connection.
3. Settings you should not rush to change
Many users see that the connection is failing and immediately start changing parameters such as port, transport protocol, TLS, SNI, and UUID. Unless you clearly know what the node provider requires, it is not recommended to manually change these items. Fields in protocols such as VLESS, VMess, and Trojan must match the server side; random changes will only make the connection harder to troubleshoot.
Safe actions you can try include re-importing the subscription, switching nodes, clearing the DNS cache, restarting v2rayNG, and restarting the phone. If you are using a manually copied share link, it is recommended to copy the full link again to avoid missing characters.
4. Troubleshooting order if it still won’t connect
- Update to a newer version of v2rayNG; older versions may be incompatible with some configurations.
- Turn off your phone’s power-saving mode and allow v2rayNG to run in the background.
- Keep the default routing mode in v2rayNG settings, and do not enable complex traffic-splitting rules at first.
- Try testing 2–3 nodes from different regions or using different protocols.
- If all nodes fail on all networks, uninstall and reinstall the client, then re-import the subscription.
The rule of thumb is simple: if switching nodes works, it is most likely a node issue; if switching networks works, it is most likely a restriction in the current network environment; if reinstalling works, there may have been a client cache or configuration issue. Handling it in this order will cover most cases where v2rayNG won’t connect, while keeping the risk as low as possible.
One final reminder: free nodes can be used for temporary testing and learning configuration, but stability will be affected by the network, routes, and number of users. When failures occur, do not keep trying the same node repeatedly. Following the steps to switch nodes and network environments will be more efficient.
