5672 is merely the AMQP port. You need to make sure that it can access
epmd on my-server-name which should be port 4369. See the man page for
epmd if you need to change that.

If you have no firewall between these machines at all then it would
likely be some sort of DNS resolution issue, but seeing as you can ping
the server, that seems unlikely.
