I just tried upgrading the software, and still the problem persists. I am trying to connect to a Windows 8 laptop from Mac El Capitan which has the latest version of TV. The PC has a recent version, but not the latest. It used to connect without problems.
I've seen this error before and usually in the past I just wait a while and it eventually connects. But this has been for several days and it's still not connecting - even after this update just now.
[doublepost=1482363890][/doublepost]Just a minor update to this...
I've checked this out on 2 computers now. On the Mac, I see the device and get the error. On a different computer (Windows) the computer I want to connect to is appearing as offline.
So there is clearly something weird going on. So, either it's online, or it's offline.
Given the connection error window, I'm guessing there is a problem with the connection and/or it's current offline. But who knows.
my 2 cents.
