"Communications link failure" when creating connection to mysql DB

I’m a new Katalon user, with version 8.6.8.
I’ve copied the same DB connection parameters as a work colleague for whom this works.
I have the JDBC driver installed and configured, just like my colleague.

When I press “Test Connection” on the Project->Settings-Database screen, I get:
“Connection failed! Communications link failure”.

The DB credentials are correct

Thanks for your help!

Please connect your database team and check all information is correct.

Thank you for your reply.

but as I mentioned the DB credentials are correct.
the only place I cant connect to the DB is in katalon.

make sure you have downloaded and imported mysql connector properly in your project, see:

you can also try to connect to the DB with another tool, e.g DBeaver, to make sure you don’t have issues with your networking:
