Sandmann79 - problems after a correct installation

  • Hi, I installed Sandmann79, raspberry pi 3 B+, and I followed the instructions of the case. The widevine installation was successful, so it communicated to me from the screen. I inserted the pin for Amazon Prime and also here I am told that it is correct.

    But when I go to open any video I am told that the request is not executable.

    I would need more clarification and thank you in advance.
