External users can't connect to group chat service

Hey team,

Currently running Openfire 4.5.1

We currently have 2 group chat services ‘Conference’ and ‘conference 2’ running on the same openfire server.

External networks are trying to connect to our Openfire server, all of these networks can connect to ‘Conference’ no problem, but no matter what I try, no once can connect to ‘conference 2’.

Am I missing a setting somewhere?

Thanks!
