"The software clearly shows that it is connected, but the webpage cannot be opened" is the most frustrating situation. The cause may be in the node, in the local settings, or in the system time. Press below From simple to complex In order to check, most people solve it in the first three steps.
Do one thing first: Switch the bottom column "System Proxy" to "Clear System Proxy" and see if you can open domestic websites (such as Baidu) normally. If it can be opened, it means that there is no problem with the computer's own network. The problem lies in the proxy configuration; if it cannot be opened, it means that your computer itself is disconnected from the network. Repair the network first.
1Is the system agent enabled or not?
The most common "fake connection": the node is selected, but you forget to switch the bottom column "System Agent" to "Automatically configure system agent". It looks connected in the software, but in fact the browser doesn't use a proxy at all. Confirm this step first.
2Try changing nodes
The node you selected may happen to be down or under maintenance. Select all nodes button Ctrl+R Measure the true connection latency (see Speed test tutorial), pick a green one with low latency and re-select it. if All nodes time out, the problem lies in the next few steps.
3Check computer system time
This is the number one hidden reason why VMess nodes cannot connect. The VMess protocol relies on timestamp verification. If the computer time is too different from the server time (more than 90 seconds), the handshake will fail, and the performance will be "connected but unable to transmit data."
- Right-click the taskbar time → "Adjust date and time" → turn on "Automatically set time", then click "Sync Now".
- Users of dual systems are especially prone to time confusion, so synchronizing them once is basically enough.
4Check to see if the kernel is actually started
v2rayN is just an interface, the real work is the underlying Xray kernel. If the kernel is not up, it will be useless no matter how normal the interface is. Look at v2rayN main interface Log area at the bottom: Normally, there will be words such as "Xray started successfully"; if a full screen error message (such as port occupation, configuration error) is reported, it means that the kernel startup failed.
- Port occupied: reference Port conflict resolution, change a local listening port.
- The kernel file was deleted by anti-virus: restore it to the anti-virus whitelist
xray.exe, and add the v2rayN folder to trust.
5DNS and browser caching
- Occasionally DNS pollution causes domain name resolution errors. You can fill in a reliable DNS in "Parameter Settings → DNS", or turn on Tun mode and let the kernel take over the DNS.
- Use the incognito window of your browser when troubleshooting to avoid caching from interfering with judgment.
- If the company VPN, other proxy software, or a proxy plug-in is installed in the browser at the same time, there will be a fight. When troubleshooting, turn off all of them first, leaving only v2rayN.
6Still not working?
If you have tried all of the above and it still doesn't work, there is a high probability that it is a problem with the node itself (proxy providers flight, package expiration, or being blocked). Change your subscription or contact your service provider to confirm your account status. If the software cannot be opened at all or crashes, it is another type of problem.
