Why Am I Getting a 'Lost Connection to MySQL Server' Error?

Understanding "Lost Connection to MySQL Server" Error

If you encounter the error "Lost connection to MySQL server at 'reading initial communication packet', system error: 0" while attempting to connect to your database, several possibilities could be the cause.

Firewall Interference

As suggested in the community discussion, a firewall may be blocking the connection. Consider adjusting your firewall settings to allow access to the MySQL server.

MySQL Server IP Binding

Your MySQL server may be bound to the loop-back IP address (127.0.0.1) by default. This restriction prevents external connections. To resolve this:

• Upload the script to the webserver. The server running your MySQL server should also host the script attempting the connection.
• Use 'localhost' as your server host. Maintain 'localhost' as the server host even if the script is on the webserver.

Other Possible Causes

• Check if your MySQL server is running and accessible.
• Verify that your script is using the correct database credentials.
• Consider checking your network connectivity and DNS settings.
