org.postgresql.util.PSQLException: Connection refused

You ran your application to connect to your Postgresql database and received the following exception.

org.postgresql.util.PSQLException: Connection to 129.178.32.11:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.                at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:285)

After you have ensured that the hostname and port are correct and the exception remains you need to modify the postgresql.conf file.

         Uncomment and change listen_address='localhost' to listen_address='*'.

Then check the pg_hba.conf file to ensure your host is allowed to connect to the database by changing IPv4 and IPv6 local connections to:   host   all   all   all   trust

And restart your Postgresql database.
