Courses not working

Hey guys. I just became a premium user and wanted to learn new information about Unity in "premium courses". But this course and others not working: https://learn.unity.com/course/unity-game-dev-course-programming-part-1?language=en

Error:
"The media could not be loaded, either because the server or network failed or because the format is not supported"

 

seems to work here, what web browser you are using?

 

this is strange... i using google chrome. But this lesson really work on my mobile device. Thanks man.
UPD: the problem is AdBlocker.

 

have the same issue. works on edge. doesn't work on Google Chrome. Disabled AdBlocker but nothing changed. I'll try to restart the PC (I already restarted Chrome)

Edit: I had to uninstall adblocker because even setting the learn.unity.com domain as safe blocked the movies.
