Yes Sushant, I added the Apps IP ranges in pg_hba and restarted the PG services.
Port is 5432 and also postgresql.auto.conf is having same port.
Contents of postmaster.pid
$ cat postmaster.pid
26802
/var/lib/postgresql/12/main
1603903729
5432
/var/run/postgresql

Hi,
You might have already checked but I would suggest checking that the IP address in pg_hba.conf file is the same client IP for which you have received the error. For eg. when the error is Connection to 192.168.42.123:5432 refused. I would add 192.168.42.123 in pg_hba file. This can be your application gateway which may differ from the actual application server IP.
Please check if Postgres is accepting a connection on port 5432. It may happen that postgresql.auto.conf may have a different port specified in it. You can cross verify entries in the postmaster.pid file for listen_address and port number on which Postgres instance is accepting the connection.
Regards
Sushant

Hi Experts,
We are trying to connect from Java(Microservices) applications to Database and getting below issues :
org.postgresql.util.PSQLException: Connection to XXXXXXX:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
Please suggest your inputs and suggestions for solution.
The things I did :
- Firewall/Ports are open from DB server for inbound traffic.
- Added application IP ranges in pg_hba.conf file and restarted the Postgres instance.
- The listen_addresses=’*’ is set to.
- $ lsof -n -u postgres |grep LISTEN
postgres 26802 postgres 3u IPv4 19104770 0t0 TCP *:postgresql (LISTEN)
postgres 26802 postgres 4u IPv6 19104771 0t0 TCP *:postgresql (LISTEN)
- $ netstat -ltnp | grep postgres
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 26802/postgres
tcp6 0 0 :::5432 :::* LISTEN 26802/postgres
- $ cat /etc/postgresql/12/main/postgresql.conf | grep port
port = 5432 # (change requires restart)
#ssl_passphrase_command_supports_reload = off
Thanks
