Ok..digging some more into the forums I found this reference you had posted earlier @giacomo
The ejabberd web interface is disabled by default, but can be enabled:
config setprop ejabberd WebAdmin enabled
Then you can access as email@example.com, for instance, at https://ip-address-or-domain:5280/admin/
So I've issued that instruction on my nethserver and no errors were reported. But when I go to the admin page as instructed I get a 'Site can't be reached' error. I don't think my ejabberd is working properly on my server.
Any ideas what I can look at next or do to solve this?
