ERR PROXY_ CONNECTION_FAIL

The "ERR_PROXY_CONNECTION_FAIL" error message typically occurs when a connection to a proxy server fails. This can happen for several reasons, such as:

1. Incorrect proxy settings: If the proxy settings are incorrect or outdated, the connection may fail. Check the proxy settings in your browser or network settings and make sure they are correct.

2. Proxy server is down: If the proxy server is down or experiencing issues, it may not be able to connect to the internet. Contact your network administrator or internet service provider to confirm if the proxy server is functioning properly.

3. Firewall or antivirus software: Sometimes, firewall or antivirus software can block the connection to the proxy server. Temporarily disable the software and try to connect again.

4. Network connectivity issues: If there is a problem with your internet connection, the connection to the proxy server may fail. Check your network connectivity by trying to connect to other websites or services.

5. Proxy server is blocked: In some cases, the proxy server may be blocked by the website or service you are trying to access. Try accessing the site or service without using the proxy server.
