But you did get the code (scan QR code) with your OTP/Google Authenticator? It just is that the site doesn't accept the OTP code generated by it?
Well the thing was that no qr code was showing only a link and i noted down this code an put it manual into my phone.
This is where i think it went wrong.
No i did not copy the link or made a printscreen.
Now i created a new account and was able to link my addon for chrome (google athen.) with this account.
So i think i must have put some wring characters into the manual part of the GA setup
Hope they can fix this.
