Why Am I Getting 'Lost connection to MySQL server at 'reading initial communication packet', system error: 0' When Connecting Externally?

Resolving "Lost connection to MySQL server at 'reading initial communication packet', system error: 0" with External Connections

When attempting to establish a MySQL connection using an external IP address, users may encounter the error: "Lost connection to MySQL server at 'reading initial communication packet', system error: 0." This issue typically arises when the MySQL server's IP address is restricted to local connections.

Possible Solutions:

1. Firewall Restriction:

As suggested in the community, a firewall may be blocking the MySQL connection. Verifying firewall settings to ensure that the necessary ports (usually 3306) are open for MySQL traffic is crucial.

2. Loop-Back IP Binding:

Another possibility is that the MySQL server is bound to the loop-back IP (127.0.0.1), limiting access to local connections only. To resolve this, the script should be uploaded to the webserver hosting the MySQL server, and 'localhost' should be used as the server host.

Additional Considerations:

• Ensure that the username and password provided for the connection are correct.
• Verify that the MySQL server is running and listening on the appropriate port.
• Check for any network connectivity issues that may interfere with the connection.
