Playback error from simlinked folder

[eni]

Hi there,

I hope that I am just blinded from trying since yesterday, so hopefully just need a little nudge. Yesterday I tried and searched around the web so much, that I now have a hard time retracing all my steps. I'm completely new to media servers and also just got my first TV after not having one for many years  

Jellyfin 10.10.3 on Linux Mint 21.3 Cinnamon. 
I followed the instructions for the debuntu repo method and it worked out of the box for me.

The issue occurs regardless of client.
Media files I put directly e.g. under /media/movies are read and played just fine, locally in browser and on TV.

Issue:
I'm trying to have jellyfin play files from my external media HDD. 
So I created e.g. /media/anime to show the files in /media/eni/externalHDD/anime when mounted, via symlink.
I did this during one of dozens tutorials yesterday when a direct link to the HDD just would not work out.

I've set the permissions for those folders, just as for the working direct folder.
ls -ld anime/
drwxr-xr-x 2 eni jellyfin 4096 Jan 17 17:53 anime/

The files are read and shown after re-scanning the library, including jellyfin giving them new pretty cover images, but not played. It just says fatal playback error.

Shouldn't this work? Am I missing something? 
Thank you in advance.

Symlinks do not bypass access restrictions. USB hard drives are usually mounted with an ACL applied to them.

Your options are to manually mount the USB hard drive or to remove the ACL.

To remove the ACL, use this command.

Code:

sudo setfacl -b -R /media/eni

To manually mount it, read my guide here.
