Error with playing videos

Some videos won’t play, “Video not available” will appear on screen white font on grey background, here’s one of the videos that won’t play https://www.youtube.com/watch?v=FLk629R3oG0&t=119s I’m the only one who can’t watch it and me & my friends all live in the same country, I’m using mozilla firefox w/ DuckDuckGo browser also tested with google I dunno if it changes anything but doesn’t work anyway

Thanks for your feedback. The video you posted works for me but i know about this issue in general. Are you signed into a Youtube account while using Watch2Gether? Another reason could be one of your browser extensions (adblocker for example) Try disabling them one by one and see if that makes a difference.
