SOLVED: Jellyfin can access Mounted NFS but FFMPEG says no such file

[CountParadox]

Hi guys;

I have JF installed in a windows VM. The service runs as a user account, 
I can login as that user account, and I have a mounted smb share, with full permissions and everything correct (im fairly sure at least...)

JF has no issues indexing the media and can see and modify it (eg delete files) no issues. 

But attempting to playback any content, does not work. 
JF says that there is a problem with the file, and checking the logs shows FFMPEG saying the file does not exist.

eg:

file:M:\Movies\Barbie (2023).mkv: No such file or directory

While the file is indeed, exactly there.


I have googled around but the info I am finding does not seem relevant.

Anybody have any ideas ?
