Why Can't I Connect to My MySQL Server Using a Live IP Address?

Understanding the "Lost Connection to MySQL Server" Error

It appears that you are encountering the error "Lost connection to MySQL server at 'reading initial communication packet', system error: 0" when attempting to connect to your MySQL database using a live IP address rather than localhost.

Firewall Interference

One potential cause of this issue is firewall interference. As suggested by a previous community member, your firewall settings may be blocking full access to MySQL. If you are utilizing a firewall application, consider checking its configuration to ensure that it is allowing access to MySQL.

Bound to Loop-back IP

Another possibility mentioned by another community member is that the MySQL server is bound to the loop-back IP address (127.0.0.1 / localhost). This can prevent external connections from reaching the database. To resolve this issue:

1. Move your PHP script to the webserver hosting the MySQL server.
2. Maintain the server host as 'localhost' within your PHP script.

By doing so, you are connecting to MySQL from within the same machine where the server is running and avoiding the restrictions imposed by binding to the localhost address.
