Lost Connection To MySQL Server At ‘reading Initial Communication Packet’, System Error: 0

This error message usually occurs when the PHP script is unable to establish a connection with the MySQL server. Here are a few possible solutions:

  1. Check the MySQL server status: Ensure that the MySQL server is running and accepting connections. You can verify this by using the command line or any server management tool.

  2. Verify MySQL server credentials: Double-check the hostname, username, password, and database name that you’re using in your PHP script. Make sure they are correct and match the server configuration.

  3. Check firewall settings: Ensure that your firewall or network settings are not blocking the connection to the MySQL server. If necessary, open the required port (default is 3306) in the firewall.

  4. Increase the connection timeout: Sometimes, due to server load or slow network, the connection might take longer than the default timeout. You can increase the timeout duration in your MySQL server configuration file (my.cnf) or in your PHP script using the mysqli.options or PDO::ATTR_TIMEOUT settings.

  5. Verify PHP MySQL extensions: If you’re using the deprecated MySQL extension, consider switching to either mysqli or PDO. Make sure the appropriate extension is installed and enabled in your PHP configuration.

  6. Check server logs: Examine the MySQL server error logs for any relevant information about the connection issue. The log files are usually located in the MySQL data directory or specified in the my.cnf configuration file.

By following these troubleshooting steps, you should be able to resolve the "Lost connection to MySQL server" error.
