Hello everybody,
I’m new here…

I have a question : What am I doing wrong … I can start the meeting in a conference room and see me … but if I want to send a message I get the message that the message was not sent. Other users I can not invite , the space will created stands

Log in I see this error message:

“<message to="” from="" type=“error”><error code=“404” type=“cancel”><remote-server-not-found xmlns=“urn:ietf:params:xml:ns:xmpp-stanzas”/>"

Can someone please help me?
