Since upgrading my F2-424 to TOS version 7.0.0791, Jellyfin real time monitoring does not work.
Jellyfin real time folder monitoring fails with access error below
[2026-07-24 08:37:16.123 -07:00] [INF] [1] Emby.Server.Implementations.ApplicationHost: Running startup tasks
[2026-07-24 08:37:16.124 -07:00] [ERR] [10] Emby.Server.Implementations.IO.LibraryMonitor: Permission error for Directory watcher: "/Volume1/aaa"
System.UnauthorizedAccessException: Access to the path '/Volume1/aaa' is denied.
---> System.IO.IOException: Permission denied
I have assigned the Jellyfin application account read/write access to the '/Volume1/aaa'. Real time folder monitoring still fails!
I even did a complete NAS factory reset. Rebuilt my NAS from ground up & real time folder monitoring still fails.
Manually clicking Dashboard | Library | Scan Library works just fine with no access denied error
Thanks in advanced for any help.

I fixed my issue by deleting & re-creating a New TNAS share.
1 - I deleted the TNAS share which deleted all data (5TB) in the TNAS share
2 - I created a new TNAS share
3 - Restored data from an external backup. Copied data backup (5 TB) to new TNAS share
The Jellyfin Realtime Monitoring working. No more access denied permission error.
