Open the remote login, set the login user to add the administrator of Mac on the right, and then click the terminal. Enter "ssh localhost" and enter yes. Enter the administrator password, and then you can open port 22.

Port 2222 is usually the default port number of DirectAdmin management panel. By default, all websites with DirectAdmin control panel can open the DirectAdmin control panel of the host by directly entering the port number 2222 after the domain name.

Seeing that this IP (124.115.193.73) has 2222 ports, it may be because this website uses DirectAdmin control panel. If you are a host company, the port number can be modified in WHMCS.
