Unity Learn Content Blocked By CORS Policy

For a few weeks now, I wanted to return to Unity Learn and continue with my learning, but for some reason, the videos do not load. When I inspect the page, I encounter a problem with CORS policy in which it does not allow the videos to play. The strange thing is that in the past Unity Learn worked well for me, but not now. I have also been looking to see if anyone else has had this problem and the solutions they gave do not work for me (clear the cache, use another browser, create another account) also the problem is only on my computer, because if I use another device everything works. If anyone knows how I can solve this, please help me.

PROBLEM:
Access to XMLHttpRequest has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
