Unable to update libraries with new media

Sorry to spam with the same problem, but I asked on a Friday evening and it got no traction so I’m asking again.

Hi all, I realized tonight that newly added media hasn’t been showing up in Plex for the past ~7 days or so. Media plays as expected, but new media doesn’t show up when scanned.

I did the usual first steps to troubleshoot:

  • Restart PMS service, rescan libraries. No good.
  • Restart server, rescan libraries. No good.
  • Log out of PMS, log back in, rescan. No good.
  • Double-check scan directories.
  • Remove a file manually, re-add it, rescan libraries. No good.

I enabled debug and verbose logging and found that the new files are all triggering similar errors:

I searched Plex forums and found a number of similar problems, but none of the suggested fixes resolved my issue or seemed to be applicable based on OS.

  • Verified that secure connections was set to preferred, not required.
  • Verified firewall holes in place (and even dropped firewall completely to no avail)
  • Verified that I was able to access 127.0.0.1:32400. However I get an “unauthorized” error on http://127.0.0.1:32400/library and on library/changestamp

I’m running Windows 10 Pro, PMS version 1.10.1.4602, and am not aware of any updates (Plex or otherwise) going through in the past week that might have caused the behavior.

Any help that could be provided would be very appreciated. Thanks!

So to hit /library or /library/changestamp I use a program like postman and you need to add a token and stuff and this is my output from /library/changestamp

If you know what you are doing and want to test that for ■■■■■ and grins and see what you get, Ill look around and see if I can find any other related issues or other clues on what to try next.

first recommendation is to check the file names – plex can be particularly picky when it comes to file names / folder structures around tv shows.

should be D:\Video\TV\The Good Place\Season 02\The Good Place S02E11.mkv (season folder should use a 2-digit season number and just to be safe drop the optional suffix to avoid Plex gets thrown off or accidentally runs into another pattern they’re looking for)

I’m aware everybody feels like this is a pain but I’ve also noticed that a single invalid name can result in a complete roadblock.

Personally I’d try to fix the above first and maybe do the plex dance (move content outside your library folder, re-scan the library, empty trash, clean bundles, move content back to the library folder, re-scan again).
From what I could find in the forum and on reddit, there’s a mixed record – some people actually had issues with their server’s network stack (/etc/host or firewall), for others PMS got really badly stuck due to some trivial issue (such as naming).

For anyone in the future who finds this and is trying to find an answer, my specific situation was pretty unique (not to mentioned caused by myself directly) and was resolved thanks to a generous/handsome fellow in the original thread here.
