Error: "Playback Failed"

Hello there, i started to get the Error which is shown beneath today. Ive been watching this show for like a week now and it randomly started mid-show, which is quite weird..
Does anybody have an idea on what the problem could be? i changed literally nothing.
Error is the following:

Playback Failed
Playback failed with error "loading failed". Retry with transcode? (Note this may hang the player.)
