Why Can't My Script Connect to MySQL Server Using My Live IP Address, But Works with Localhost?

Lost Connection to MySQL Server Issue

The error message "Lost connection to MySQL server at 'reading initial communication packet', system error: 0" indicates a connection problem between your script and the MySQL server. When attempting to connect using your live IP address, you encounter this issue, while using localhost works seamlessly.

Potential Solution: Firewall Configuration

It's possible that your firewall is blocking the MySQL connection. As suggested in the forum, check your firewall settings and ensure that it allows full access to MySQL. If necessary, modify the settings to allow communication from the script's IP address.

MySQL Server Bindings

Another potential cause is that the MySQL server is bound only to the loop-back IP (127.0.0.1 or localhost). This restriction prevents external connections, causing the issue when you use your live IP address.

To resolve this, consider uploading the script to the webserver hosting the MySQL server. By maintaining 'localhost' as the server host in the script, you can establish a successful connection because the script and the server reside on the same machine.
