The problem seems to be caused by videos with multiple pre-rolls.
For example, The Gilded Age showed a pre-roll for Barbie movie which pops up in the main "Home' browser window. Then it also showed an optional recap for the show. At that point, the browser window spins off into the 'Failed to load URL https://play.max.com/ with error ERR_TOO_MANY_REDIRECTS (-310).' although the download progresses in the background.
It seems this can sometimes get the system stuck and attempts to access it later fail.
Clearing the cache fixes it for me... just trying to help the devs locate the possible failure point
