If you open a terminal, cd <location> and run ls -la, what do you get? Who’s the owner and what are the permissions of the subdirectories?
Are there any errors in the Jellyfin interface? Have you checked the logs?
777 permissions are a bit overkill, I think 755 should be enough, since you don’t need to “execute” mkv files.
