Help! I cannot get Facebook to work with Webcaster 2

Although the pairing process appears to work correctly I am unable to stream. Facebook neither sees the Webcaster as a Camera nor allows me to Connect via the API configuration page. What am I doing wrong?

If you are trying to start the stream from the Facebook side, you cannot do so, the Start/stop and destination selection is controlled on the Webcaster itself.
