Can' start the HUE Assistent on 2.0.0-alpha.10

I have installed the latest Alpha Version today and would try to play with HUE (again). In Alpha 8 I do that to, but I delete it. Anyway... If I click on the Assistent Button, it open the Popup but if I click on "Continue" nothing will happen. I try it under Safari and Opera under Mac OS and Safari on iOS.

Thanks for the feedback. Where I can found the fix? Or did I need to wait for a next update?

I don't understand how Github works.
