Updated the server to Version 3.20.5 the other day and now watch later videos just say "the plex server is not responding" When I try to play them. whether I'm doing it at the server itself or a separate client, it doesn't matter. The videos are all from youtube and from different youtube channels, the videos are still available on youtube.
Yes. I’m having this issue
Same thing on Mac server Version 126.96.36.19972. All "Watch Later" movies will try to load for long time and then display error message. I checked and the movies are still available on youtube.
If this is with
a) YouTube videos, and
b) while using the Watch Later function in the Plex Web client (in Chrome or Firefox),
then see: https://forums.plex.tv/discussion/comment/1521792#Comment_1521792
