It works on normal Chrome. Netflix support told me its prolly you... I cleared cookies, i restarted PC.. i turned off all extensions, i do not have it as a bookmark... - still nothing.. this is the page of the error : https://help.netflix.com/en/node/56434
Can confirm this bug & just sent feedback via the Smiley: every video on Netflix fails to load with the exact same error as OP. This bug is totally out of the blue as yesterday, it worked great. Works in Chrome, not in Chromium Edge.
Some weird new bugs with Chromium Edge & videos lately. I sincerely hope it's not due to adding back "PlayReady" or Widevine DRM.
