DRM_ERROR / DRM_KEY_SESSION_ERROR in safari 18 and 26 (tahoe)

HI,

It started last februari when I updatet my Dutch Macbook M1 during a vacation in the Philippines. I got this message (DRM_ERROR / DRM_KEY_SESSION_ERROR) in every streaming platform (Netflix, Disney and prime).

I deleted all the cache and history within safari, no luck

i have no VPN or ad-blockers.

So to solve the problem for now I downloaded firefox and watching on that browser works just fine.

Now after updating sequoia to Tahoe I had my hopes up that this would fix the DRM issue....but unfortunately not. Still getting the DRM error on every platform.

Who has any idea or suggestions on how to solve this problem

Greetings.

Michael
