RTFM!!!
I wasn't sure if there was an implicit deny for external connections. There is not!

Explanation

TLS/SSL certificate file was not successfully loaded.
Solution

Check the file ejabberd.pem exists, is readable by Erlang and the route is correctly specified in your ejabberd.cfg configuration file.

I followed the instructions and added a server.pem file in the install doc.
