Plex does not show new movies

Plex Media Server NAS & Devices
1

Server Version#: PlexMediaServer-1.15.5.994-4610c6e8d-x86_64

I just bought a new Synology DS218+ and installed Plex on it. I created a movies library in the /volume1/media/movies location. Each film I added was not showing up even when I did all of the following things.

  • Scan library files
  • Optimise database
  • Clean bundles
  • Refresh all metadata
  • All files are perfectly named (with dates), each inside a folder named the same thing.
  • Restarting server
  • Settings -> library -> scan library automatically / run a partial scan when changes detected / scan library periodically
  • Settings -> agents -> movies -> ticking and unticking local media assets / changing the order of them
  • If I change to folder view, I can see the folders, but not the movies when I click inside.
  • Permissions for the plex user and admin are all read/write

I examined the logs and couldn’t see anything suspect. I ended up deleting the library and re-adding it, and magically all of the movies appeared! I then tried to add some more and they would not appear. I also found that if I edit the library and change the agent, either from Plex movie -> The movie database or The movie database -> Plex movie , the movies all appear. I have no idea why this works, but I would love for them to appear automatically.

I looked at the following topics on these forums and think they might be related (here and here). When ssh-ing into my server and attempting the following I get a 401 unauthorised error: curl http://127.0.0.1:32400; echo

Any help would be greatly appreciated, this issue is driving me insane.

Another look at the logs for a file that is not appearing shows me:

Hey, thanks for your reply. Inexplicably when I followed the plex dance steps it started working and instantly recognising new movies. I had gone through the plex dance steps before and nothing came of it so I am mystified that it’s started working now after trying to figure this out for >6 hours. Again thank you, and I hope it continues to work.
