Jellyfin library empty on Synology NAS

[aptmx]

My bet is that it's the user you're running it under.
Just in case (since you state you have the correct UID + GID), your provided example has "--user 1026:100" which is the same one as in the guide. You probably copied this over from that and probably isn't linked to any user in your actual server.

You can try:

• Changing the UID+GID to the correct user on your NAS
  
• Change the UID+GID to root (to see if this is the issue)
  
• Remove the "--user #:#" line to have Jellyfin run as root anyway

Edit:

Looking at the picture of your container's volume settings, you linked the folder wrong.
You have it linked to the directory "/Media".
Turn off the container, then edit the path to be "/volume2/Media/".

Can you post the actual docker run command that you used?

Hi.  I did get my actual user UID + GID.  It just happened to match the one in the guide.  I will try removing the user line like you stated.  The actual run command is what I did post.  (it is from the guide with my specific settings modified).  I will also try editing the container with that correct path.  Thanks for the advice and I will report back.

No luck.  I uploaded pictures of what I tried and Jellyfin still does not see anything.  When I click add folder in the container settings and select my media folder, it just shows up as /Media regardless.  I tried adding /volume2/Media/ to the text box next it and re-adding the library but it still sees nothing.  Not sure how to get root UID and GID and if I remove the line entirely, I have to create the entire container again?
