Unet Lobby variable missing and no client instance on clientside in lobby

I am trying to use unet with lobby. Suddenly it is broke for me. When client connect to host:
on hostside all work fine.
on clientside there is no line with client name. There is line with host name, but not with client and no join button.
But if client try to start own game, then stop it and connect to host again - it is all works fine on both sides.
I think when player start host, there is some variables to change their values from null, may by I am wrong.

I have solved the problem. In Click Listener on Join in room button just add some values in custom variables from lobby manager. A have added values to all my variables and it is work fine now.
