Pidgin not connected to Openfire

Hello everyone.
Openfire Installed on Ubuntu 16.04
I am trying to connect via Pidgin over IP but an error “connection broken” and “can not connect”. If prescribe in addition to IP and port yet, it gives “invalid XMPP ID”

Settings pointing right. Because everything is connected on other computers. And I have not specifically connected = (

Help me please. Which logs to show you?
