If there was a message about a disallowed connection in the broker 
logfile of the node that you try to contact then the erlang cookies are 
not synchronised. Make sure the erlang cookies are the same on all nodes 
to be clustered.

You should also make sure that the hostnames of all nodes resolve to the 
same addresses on all hosts.

If there are firewalls between any hosts then make sure that the 
required ports are allowed. The clustering guide explains how to do that 
and how to set up clustering between different hosts.
