Is there anything else that might be preventing access? Are any other
applications on these nodes able to communicate? Clustering will not
work unless TCP/IP networking is in place.

You don't say which port you used but the EPMD and AMQP ports at least
should be open and the failing connections above need to succeed before
clustering will work.

You would perhaps need to edit this to set up hostname resolution, e.g.
to set up a different resolver or search domain. If you are confident
that name resolution is working correctly then you don't need to edit this.
