Just from a quick look it appears you are creating a GroupChat room with the name 123@127.0.0.1 and then attempting to join a room with the name “andres”.

This isnt going to work.

You’'ll need to join the room with the same name you used to create it.

Also I wouldnt use the GroupChat class, far better to use the new MultiUserChat class
