I just installed the Java and PostgreSQL environment on a server (for remote testing) CentOS 7
From the command line using ssh would seem that there are no problems in the sense that I can access the user "postgres"
But when I try to access to PostgreSQL via PgAdmin4 I get an error, or get
Unable to connect to server: could not connect to server: Connection refused Is the server running on host "81.xxx.2.xx" and accepting TCP / IP connections on port 5433?
I thought it was the firewall so I typed
firewall-cmd = public --zone --add-port = 5432 / tcp --permanent
but my server get
FirewallD is not running
Any idea to solve the problem ????
