How can I verify if the MySQL server is configured to accept remote connections and resolve error 2003?

By default, MySQL might be configured to only accept connections from 'localhost'. To allow remote connections, you need to edit the MySQL configuration file (often `my.cnf` or `my.ini`). Look for the `bind-address` directive. If it's set to `127.0.0.1` or `localhost`, change it to `0.0.0.0` to allow connections from any IP address, or to the server's specific network IP address. After changing the configuration, restart the MySQL server.
