New Plex-server doesn't find all TV Shows

Server Version#: 1.25.3.5409
Player Version#: 4.69.1 (plex web)

Since we completely reinstalled Plex, our server only finds half of our TV shows. (both the old and new series scanner find the same amount) The old server, which was already six years old and migrated continuously, found everything. We use Jellyfin as second server, this server finds all our shows without problems.
A strange example is the series “Manifest” in season 2 plex recently finds only 3 episodes, although all episodes are named after the same pattern.

We created a second library on a new Rocky 8 linux VM with the same data mount (NFS) for testing purposes. Performed the basic setup and created the serien library, There it finds 294 TV shows, our main plex server finds just 289 TV shows out of 443 TV shows at the moment.
The two servers do not even find the same shows. To me this looks like sporadic errors of the plex tvscanner. Our library is very large and consists of about 30 TB of series data. Maybe the scanner is running into some kind of limit? I have attached some screenshots below.

**TV naming - inside folder it’s organised with season 01 … **

Example Manifest:

Episode naming

Does Plex list duplicate episodes/shows?

Would it be possible to see a screen capture from the root of your TV Library all the way down to showing Manifest Season 03 episodes?
(In a way so we can see the full path as well

No it does not

Yes of course,

But there are shows that even completly not pop up.. as mentioned before we have at least 443 TV shows and only 289 shows are found on our production plex environment.

Hello,

I am a new Plex user, and I have a similar issue since yesterday after upgrading Plex Server version to 1.25.3.5409-7000.

I upgraded my libraries (switching to Plex Movies and Plex TV Series agents), and then 1 TV show (out of 23) disappeared from Plex.
This issue doesn’t seem to affect my Movies or Music libraries.

Having a very small TV Show library (23), this issue doesn’t seem to be limitation related.

A strange fact about how my TV show totally disappeared : After upgrading my TV show library, this TV Show was still there, but with only 1 episode (out of 12). When I checked my disk folder, I noticed that all files where .mp4 files except one. So I renamed all files to .avi extension, rescanned the library, and the TV Show totally disappeared. No way back, even after renaming files to mp4 again or switching back to older TVDB agent.

In plex client, when I change the display to “Folders”, Plex says my missing TV show folder is empty.
I tried to re-apply disk permission (read permission for PlexMediaServer), nothing changed.

Folder view from my Windows workstation :

Folder view in my NAS web interface :

Not a big deal for me, but just hoping my case could help solving OP issue.

Regards

PS : My plex server is installed on a Synology 218Play Nas

Update : My issue was only a naming issue.

I renamed all files, by removing the french episode name, and the TV show is now back again in plex. (ex : Top of the Lake-S101.avi)

Sorry if my issue was not related to OP issue.

Regards,

PS: it seems new Plex Server version is less flexible with non compliant file names

Make that “Top of the Lake-S01E01.avi” – keeping the episode title at the end of the file name shouldn’t be a problem. In the long run you will benefit from placing the files in season folders too, e.g.

Series   <- the folder linked to your tv-show library
  Top of the Lake
    Season 01
      Top of the Lake - s01e01 - Paradis vendus.avi
      ...

Hello,

I have the same issue, some folder are empty and other not since this update

So I did a test and created a unique including one of the empty folder like
D:\Data\Multimedia\Video\Films\Z_Partition_4\C
And my library is empty

I lost more than 2000 movies since this morning before the version 1.25.3.5409

Help please

ok apparently there must be something wrong with the new plex-server package. i have now tested a bit and maybe a there might be a hint for the developers.

the two series: 12 monkies / dead mice don’t lie, are not found by plex at all.

what i have done so far:

Result - still not recognized, even after force refresh / rescan the library / reboot the server.

I then created a new library with only this path: “/mnt/blackSTORAGE/2_serien/TV Shows” in it

However, the scanner had scanned them briefly, but indexed nothing in the existing library. I also did emty trash / DB optimization - brings no improvement.

kind regards

@deepwather : can you share your server logs from that recent test library?
@arrown: not sure this is related to your issue. General troubleshooting questions: is your server installed on that Windows machine or on a different device. Might be worth putting that post/question into a separate thread.

Try this:

Rename Manifest to Manifest (2018) {tmdb-79696} (Show folder)

Rename Season 03 [FHD] to Season 03 (Season folder)

Then do a plex dance on the entire show

Hello dane22
as described in post: New Plex-server doesn't find all TV Shows - #10 by deepwather
I already did the “renaming / fine tuning” with the programm FileBot v4.9.4 - I did it as well with manifest - but it’s not discovered by the main plex server. → It’s only descovered if i create a new TV series library with only this serie inside. → same library settings & path on both librarys.

Cheers deepwather

Did you do the plex dance?

Looking at your logs I think you might want to review some of your file naming.

Example:

  • name the season folders based on the English word Season XX – not _Staffel X - HD or _Staffel X - FHD
  • there’s a weird mix of duplicate episodes, e.g.
    • 24.S01E01.German.AC3D.DL.1080p.WebRip.x265-FuN.mkv
    • infotv-24_s01e01_720p-HEVC.mkv
  • For multi-episode files, make sure to include the proper pattern in the episode file name → sXXeYY-eZZ (I found a few occurrences where you missed the - between the first/last episode numbers in those files)
  • Preferably make sure the <show name> part of the episode names matches the base name of the show-level folder – e.g. if the show is named The Office (US), name the episodes The Office (US) - sXXeYY - optional information.ext (where XX is a placeholder for the season number, YY for the episode number and .ext for the file extension)

The file names are close enough that Plex COULD under certain circumstances digest them. I suppose it’s the entirety of the different deviations that could throw Plex off. Therefore I suggest you fix your file names / folder structure before testing this again.

As per @dbirch’s suggestion… after so many changes it will be best if you can do a full Plex Dance before rescanning the library files (or test things with a new library).

Edit:
some more examples of bad names:

  • Community > Staffel 01 > ComIDL.01.avi → should be: Community > Season 01 > Community - s01e01.avi
  • Heartland > Staffel 4 > g-heartland.s04e01-xvid.avi → should be Heartland > Season 04 > Heartland - s04e01.avi
  • Heartland > Staffel 5 > crisp-heartland-s05e01.avi → should be Heartland > Season 05 > Heartland - s05e01.avi
  • Akte X > _Akte X - Staffel 10 - HD → should be Akte X > Season 10

Those types of names are all over the place.
In case you had already started cleaning them (given your screenshots don’t show any of those examples)… doing a Plex Dance should help Plex picking those changes up.
If the given examples above are the result of your attempts to rename your files with Filebot, you need to review the naming schema applied in Filebot!
