Chat no found

I try to use the chat from the application. I have registered a Gmail in which I always have online contacts for chat but the chat always appears to me disabled or not connected.

Attached images of the version and the case so you have a better idea.

Any solution?


Have you tried to switch your online status, to online and see if any error will appear?
If not please try it and let me know about the outcome, eventually make a screenshot of the error.
