OculusGo Motion an orientation access

 I have created many vr tours. 

Since yesterday all of a sudden there is a problem when I want to look at the tour in my OculusGo. The following message will be displayed:

your devices motion and orientation access is disabled for this web page, please access it through https

This message appears, too, if I want to see on many demosite at the net ….

Until yesterday morning in the morning I could still see everything perfectly on the Oculus Go. 

Have you already heard this problem? I can not make any settings on the browser of the Oculus Go ....

Best regards
