Cannot list muc rooms from ejabberd

I'm stucked with an error on my ejabberd server. It seems that ejabberd want to list from conference.localhost and not from my real host conference.xmpp.mydomain.com.

I used the same configuration on a other machine with no errors. I don't understand what I'm missing here

Thanx for your help

We just encountered the same issue a few days ago. We dig down to Ejabberd code. Refer to mod_muc around line 614. We found out:

  1. iq_disco_items(Host, From, Lang, <<>>, none) checks whether the available rooms in given host exceeds MAX_ROOMS_DISCOITEMS or not, which is set to 100.

  2. Following the case statement, it will further call iq_disco_items(Host, From, Lang, <<"nonemptyrooms">>, none)

    XmlEmpty = #xmlel{name = <<"item">>, attrs = [{<<"jid">>, <<"conference.localhost">>}, {<<"node">>, <<"emptyrooms">>}, {<<"name">>, translate:translate(Lang, <<"Empty Rooms">>)}], children = []}

That's where <item jid='conference.localhost' node='emptyrooms' name='Empty Rooms'/> comes from.

Solution

We decided to send disco query with RSM. It will be pattern-matched with iq_disco_items(Host, From, Lang, _DiscoNode, Rsm). Hope it helps.
