I've been recently having this situation with my older videos of this year, not too sure what to do to fix the problem, any ideas? I posted it on my channel on Dtube, uploaded it from my computer in Mp4 format similar to Youtube uploading standards. For instance my video "Overwatch Hijinks - 2" is having this problem. The video loads with an infinite buffering loop then stops with an "X" in the center of the screen followed by a red play button in the lower left corner that does nothing. I'll link the video below.
