Common Proxy Errors on macOS and How to Fix Them

- The proxy server is unreachable (server down or network issues).

- Verify the proxy address/port.

- Check your network connection.

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

- macOS may not apply proxy settings after updates or network changes.

- Go to System Preferences > Network > Advanced > Proxies, and reapply your settings.

- Disable and re-enable Wi-Fi/Ethernet to refresh. Contact ChitaVPN support if needed.

- DNS queries fail through the proxy due to incorrect settings.

- Check DNS settings in Network Preferences.

- Confirm if the proxy or macOS should handle DNS. If unresolved, ChitaVPN support can help.

- HTTPS through a proxy fails if SSL traffic is intercepted or unsupported.

- Ensure the proxy supports HTTPS.

- If it’s a transparent proxy, install its SSL certificate in Keychain Access.

- For more help, contact ChitaVPN support.
