Hi,

I'm getting the error 'org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.' error when I'm trying to run my application on docker.
Please help me with the fix.

Below are some of the details:
System OS: mac OS
postgres port: 5432

I made changes in the postgresql.conf and set listen_addresses = '*'

and in pg_hba.conf
host all all 0.0.0.0/0
changed the 127.0.0.1/32 change to 0.0.0.0/0

Thank you.
