Recipient-unavailable(404)

Hi community,

When connect 2 users in a same room, the second user connect get a “recipient-unavailable(404)”

And automatically finish.

I use muc.invite(“test2@delive/Smack”, “Welcome!”);

How I can resolve this problem ?

Why not work muc.invite() ?

and work

muc.grantAdmin("user2@jabber.org");

This form works, but the logic is wrong, not ?

Who can tell me ? I need understand Full Muc
