Sites that wont work on the Brave browser, probaly cause they noticed they couldent display add's :(
While on the page, open Brave Shields Panel, and turn off “Block Scripts” for that page. The site will hopefully load now.
When going to the URL, it won’t display the video, normaly u get advertisement before video starts, I suspect thay notice that brave tries to bypass the add, so they won’t start the video.
Issue logged for this and can be tracked here
