Since you activated admin tools for a specific site you should access it via https://yoursite.com/ee-admin or if you know the specific app you want, like phpmyadmin, then https://yoursite.com/ee-admin/pma
You will need your auth username that you either created or the global auth name and password.
sudo ee auth list global
the username is normally easyengine unless you change or add a new one.
If you are trying to access phpMyAdmin you will also need the database username and password. That info can be exposed with
sudo ee site info yousite.com
You will need the db host, normally global-db unless you have changed the configuration, the db user and the db password. If you need root level access to the db that is an entirely different topic for another thread.
It is good practice to close off tools when not needed. A quick
sudo ee admin-tools disable yoursite.com
will take care of that issue.
And now that I think about it, the ports 22222 was more of a v3 then a v4 configuration. I do not believe you need those ports open on v4 so close them back up.
