You need to connect to the port which PostgreSQL was configured to listen to,
which in the default case is 5432. If you are unable to connect, make sure
that the database is configured for that port, that the database is running,
that you are connecting to the right host and that there are no firewall rules
or similar which may block access to that port.
This is unlikely to be a bug in postgres, so you should take this question to a
more appropriate mailinglist like pgsql-general. See the mailinglist page for
more info:

If it's a managed service then I assume it's available via some form of dashboard or configuration GUI. -- Daniel Gustafsson
