I bought the Fidelio AW9000 System, installed the AirStudio App and registered at spotify.
So everything (Internet Radio or Sound Files) works fine more or less - BUT:

When I try to use spotify (username and pw), I always get an error message.
"Cannot connect to spotify"

I have a premium account and my account works if I login directly to spotify.

What could be the reason or any solution for this problem?

Thank you very much.
