The mysqld instance is listening on both port 3306 for 'normal' MySQL Protocol, and port 33060 for the newer MySQL X Protocol.

The port for X Protocol (mysqlx_port), supported by clients such as MySQL Shell, MySQL Connectors and MySQL Router, is calculated by multiplying the port used for MySQL Protocol by 10. For example if the MySQL Protocol port is the default value of 3306 then the X Protocol port is 33060.
