Since OS upgrade Jellyfin no longer sees added TV shows

I upgraded to 1.15.1.027 yesterday and since then my Jellyfin Television media folder won’t see any newly added shows. New episodes of shows with folders already established are seen fine - just brand new ones are somehow skipped.

It’s just TV shows that has this problem. If I place those new shows in another media folder, Jellyfin sees them and populates the metadata fine, however if I copy them back to TV folder jellyfin is still blind to them.

I’ve tried renaming the files, remuxing them, adding established and viewable into the new folders (which become immediately invisible), copying the new mkv file into established and viewable folders where still they aren’t viewable

Any ideas?

How did you install Jellyfin? Did you use the Ugreen version or your own install?

I’m not having this issue, but I installed Jellyfin via Portainer.

Even Ugreen’s official support seem to suggest not using their version…

Many thanks for your reply, I installed Jellyfin via Docker. What I am not clear about is whether the Ugreen OS upgrade is coincidental. If others here have not encountered a problem, it may be.

It seems to be a local issue, as I haven’t had any issues.
