Common HTTP/HTTPS Proxy Errors on Windows (v2rayN) and How to Fix Them

- The proxy server might be offline, or the address/port is incorrect.

- A firewall or NAT is blocking the connection.

- DNS or poor network can also cause timeouts.

- Confirm the server is online and the address/port are correct.

- Check firewall/NAT rules and antivirus software.

- Ensure DNS resolution works. If problems persist, contact ChitaVPN support.

- The proxy server needs a username/password, but they’re missing or wrong.

- The client configuration doesn't match the server’s authentication setup.

- If the proxy requires credentials, enter them in v2rayN.

- Re-check user/pass if any.

- If you still get errors, ChitaVPN support can help.

- The proxy uses HTTPS, but there's a mismatch in TLS settings or an invalid certificate.

- Check if the proxy’s certificate is valid and not expired.

- Make sure v2rayN and the server support the same TLS version.

- If needed, contact ChitaVPN support.

- Another v2ray or proxy process is using the same port.

- The service might be stuck in Windows.

- Close any other v2ray processes.

- Restart v2rayN or your PC.

- If you can’t fix it, contact ChitaVPN support.

- Wrong proxy address or port in v2rayN, or the server isn’t configured to handle HTTP/HTTPS.

- Double-check the proxy settings in v2rayN.

- If the server is only HTTP, make sure you aren’t trying HTTPS, and vice versa.

- For further help, contact ChitaVPN support.

- The proxy’s certificate is self-signed, expired, or missing in your system trust store.

- Add or trust the server’s certificate if it’s self-signed.

- Confirm the certificate is valid.

- If stuck, ChitaVPN support is available.

- v2rayN’s local port is taken by another app, or you lack permission to bind it.

- Use netstat -ano in Command Prompt to see what's using the port.

- Close that process or pick another port.

- Run v2rayN as Administrator if needed.

- For more help, contact ChitaVPN support.

- The proxy server refuses your request (blocked IP or invalid credentials).

- Check if your IP is allowed by the proxy server.

- Ensure the username/password (if used) is correct.

- If you remain blocked, ChitaVPN support can assist.

- The proxy server gets an invalid response upstream or is misconfigured.

- Could be a mismatch in protocol (trying HTTPS on an HTTP proxy or vice versa).

- Ensure the proxy server is actually reachable and configured properly.

- If you see consistent 502 errors, the server might be down or not forwarding traffic correctly.

- If nothing helps, contact ChitaVPN support.
