[solved] join_cluster fails on cluster setup

Hi,

I have two ejabberd nodes, ejabberd@node01 and ejabberd@node02. They were previously running in a cluster. I made the first one leave the cluster and then tried joining again.

Unfortunately, it fails with these error messages:

Using passed parameter for remote master node name: ejabberd@node02
Using commands:
/opt/ejabberd/sbin/ejabberdctl
/usr/bin/erl
/usr/bin/erlc

The network configuration of the machines is still the same as when they were clustered, so I'm not sure what the "inet_tcp",badarg could mean. Both nodes are running ejabberd 15.09.
