I think my postgres container can't accept remote connections

General

Has anybody out there ever have a message like this and if so how was it resolved?

sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server at “0.0.0.0”, port 5432 failed: Connection refused
Is the server running on that host and accepting TCP/IP connections?

Can you tell us more about how you run the container, on which operating system and when and where you see the error message?

One thing that I noticed: 0.0.0.0 should be an IP address.

Check if any firewall service can block the connection. Ensure the firewall can allow connection to 5432 port.
