PostGres DB connection on LAN

Hi guys,
I can't connect my RESOLVE WORKSTATION to a DB on a lan server correctly running postgreSQL.
the Mac mini server with postgreSQL shared DB does not have RESOLVE INSTALLED.
My society bought the APP STORE VERSION of Resolve 14, so it came without postgreSQL: I had to install it separately both on workstation and server.
so, the question is:
how can I make them communicate?
I tried to create a new postgres database on the server from the workstation but the result is:
"Failed to open database connection: could not connect to server: Connection refused Is the server running on host "10.0.1.2" and accepting TCP/IP connections on port 5432? QPSQL: Unable to connect."
I'm the system admin too and the ports are all opened.
please help, thx!
