Did you try modifying the firewall settings ? Add postgres service to the firewall. If that doesn’t work, explicitly open the port 5433 in the firewall.

How can I investigate this? > it's on 5433: Hmm, something odd there, because a port number mismatch should have resulted in psql failing to connect via unix socket either. Maybe you have more than one active postmaster? "ps xauwww | grep postgres" shows only one postgres process (and a few vaccum related) here is the full list: root@deb10tp:~# ps xauww | grep postgres postgres 825 0.0 0.1 213472 14980 ?

If you still get "connection refused" then you need to look at the kernel firewall (packet filter) settings. yes, with "-p 5433" I can connect regards, tom lane thanks
