Pgadmin 4 does not work

Hello I am new to openSUSE, and today just installed Tumbleweed, PostgreSQL, and Pgadmin 4 (all from opensuse repository). PostgreSQL is running fine, however, Pgadmin 4 does not work, and cannot connect to PostgreSQL server. Can anyone show me how to configure Pgadmin 4 to connect to server and run PostgreSQL successfully?

When asking for help, it’s usually a good idea to post any guide, tutorial or the steps you tried which didn’t work.

Generally speaking,
The following are probably good starting points for initial configuration and use

And, there seems to be several videos posted on the site.
