I can't run Spotify player correctly using QML/Qt framework on Linux 64bit

[Tarekmhnds]

Hello,
I have an application written in QML/Qt framework to perform Spotify tasks, on Linux system 64bit, with Widevine library installed as a plugin for Chromium.
In QML there is an element: "WebEngineView", which I used to create the Spotify player.
Everything worked perfectly for the Web Api requests, and the Playback sdk, and I can get the Device Id.
But, when I call "play" for a Playlist or an Album, the player worked only for 5 seconds, then it stopped with this error message:
"Uncaught (in promise) LicenseError: License URL endpoint response"
But If I create the player in Chromium, it works without this error.
Do you have any idea why I am getting this error please?
Best regards

Hello, I have exactly the same issue, I create web player in WebView (chromium) and after 5 sec. playback stops with the same LicenseError message.

It started happening after firmware update (this is app for wearable). I guess this is related to Widevine DRM, do you have any progress?

Best regards
