Netflix black screen after starting video

Hi All,

I am trying to get Netflix to work on OSMC with Kodi 18.8. I have successfully installed the CastagnaIT Netflix addon.

CastagnaIT/ installation OSMC
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install python-crypto
sudo apt-get install build-essential python-pip
sudo pip install -U setuptools
sudo pip install wheel
sudo pip install pycryptodomex

And installed the Kodi 18 repository followed by the addon itself:

I can start the addon and login to my account with the Authentication key method. After login I can select my profile and browse the list to any episode. Only after starting an episode I only get a black screen and the video/sound is not playing. I can only stop the video with my remote and return to the list.
After searching the OSMC forum and github page for the addon I have tried the following without success:

  1. Re-install Widevine by the Kodi program addon ā€“ InputStream helper
  2. disable OMX acceleration (kodi settings, video ā†’ video player)
  3. disconnect any openvpn connection (sudo killall openvpn)

Here is my full log where I try to start a video.

I get these two errors after I try to start the video:

2020-11-01 20:41:22.054 T:1378115808   ERROR: EXCEPTION: Invalid setting type
2020-11-01 20:42:29.464 T:1915843504   ERROR: Control 55 in window 10025 has been asked to focus, but it can't

Does anyone had this same problem or known how to fix the black screen/no sound issue for Netflix?

It might be a Widevine issue:

AddOnLog: InputStream Adaptive: Decrypt Sample returns failure!

Iā€™d suggest contacting the mantainer of the add-on / checking their GitHub issue tracker so if this problem has been reported recently.
