I downloaded 0.9.2.8 and am still getting the unable to communicate error. It will tell me it is connected when I initially save it, but if I leave the General Settings page and go back, then it gives me the unable to communicate error.
I downloaded 0.9.2.7 today and having this issue. I enter in my API key, it gives me the message that it is connected, then within a few hours, I get the “Unable to communicate…” error.
