Common Mistakes to Avoid

1. Incorrect Proxy Server Address or Port

Reason: You might have entered the wrong IP address or port number for your proxy server, preventing the connection.
Solution: Double-check your proxy server settings for accuracy, ensuring the IP address and port number match your network configuration.

2. Proxy Authentication Issues

Reason: If your proxy requires authentication (username and password), incorrect credentials will block access.
Solution: Verify your username and password are correct and re-enter them in the proxy settings.

3. Firewall or Antivirus Interference

Reason: Your firewall or antivirus software might be blocking access to the proxy server.
Solution: Temporarily disable your firewall or antivirus software to see if it resolves the issue, then re-enable it and configure exceptions if necessary.
