To anyone wondering why videos aren’t on the Peertube channel anymore: apparently, it’s an issue with the yt-dlp library used to sync from YouTube to Peertube. The instance I use is affected, and plenty of other VPS users seem to have the same problem.
The gist of it is: Google reports the library as a bot, and thus the sync can’t be performed. So, for now, videos will be on YT only, until this can be circumvented.
Sorry for the inconvenience!
