ERR_PROXY_CONNECTION_FAILED
ERR_PROXY_CONNECTION_FAILED Error
What This Error Means
The ERR_PROXY_CONNECTION_FAILED error occurs when the browser is configured to use a proxy server, but it cannot connect to that proxy. This is different from the proxy connecting to the website; here, the browser can't even reach the proxy itself.
Common Causes
- The proxy server is offline or down.
- Incorrect proxy IP address or port in browser settings.
- A firewall blocking the connection to the proxy server.
- Malware changing browser proxy settings to a dead server.
- VPN software failing to route traffic to its local proxy service.
How to Fix It (For Users)
- 1 Go to your browser or OS settings and disable the proxy server.
- 2 Check your VPN connection and restart the VPN client.
- 3 Scan your computer for malware that might have hijacked proxy settings.
- 4 Verify the proxy address and port if you are required to use one.
For Site Owners / Developers
- This is a client-side configuration issue.
- Ensure your users know the correct proxy settings if you require one.
When It Is NOT Your Fault
If the proxy server you are required to use is down.
Is the website actually down?
Sometimes the issue is just on your end. Check if the website is down for everyone or just you.
