Help: Can I remotely connect to the base?

Of course.

Yes, it is possible. To do this, follow two simple steps:

1. After logging in to cPanel, go to "MySQL® remote database" in the Databases section

And then add your external IP or the % sign there like this:

2. If you have files from another service provider, and the database is in WEBD.pl and you want to connect it - enter mnXX.webd.pl as the host, where XX is the server number that you will find in your hosting details after logging in to the WEBD.pl Client Panel
