Server Version#: 1.42.2.10156 Player Version#: 4.147.1 I have two plex servers each pointing to the exact same libraries. Both are ubuntu 24.04.3 LTS running the same PMS versions yet one server has the errors below logged each day and the other server does not. I don’t understand why they are n…

Possibly different DNS server are used by the two machines. One might prohibiting access to the metadata server of Plex. Try forcing them to use 1.1.1.1 or 8.8.8.8 instead Maybe different metadata agents have been selected for the two libraries?

Both get the dns server from the router, which points to google’s 8.8.8.8 Both have the same agent and scanner, Plex Movie, but I did notice that the one that doesn’t have the error does not have prefer local metadata checked, the other one does.

Crap, let me correct that. I looked at the Movie libraries, the error is on the TV libraries. Both have the scanner set to Plex TV Series and the agent to Plex Series and the local metadata settings are the same.

Check the paths added to plex, and file naming. If you have /sd01/media/tvshows/a/A-Team and one library points to /sd01/media/tvshow and the second points to /sd01/media/tvshow/a you will get different matching. Same with file names.

The mounts are NFS mounts and in fact the paths are different for the two machines. Machine with no error has /mnt/Elements20T/TV/Laid/Season 2/Laid - S02E04 - Episode 4 WEBDL-1080p.mkv Machine with error has /mnt/nfs/Elements20T/TV/Laid/Season 2/Laid - S02E04 - Episode 4 WEBDL-1080p.mkv Though I…

[image] helphand: Though I’m befuddled as to why the paths would matter since the two PMS installs aren’t talking to each other. Paths and what is setup in your add folder section of your library impact how the server parses TV show names. As time passes the parse/scanner Plex uses evolves. …

Plex Media Server Logs_2025-11-20_10-34-32.zip (6.1 MB) These are from the machine that is give the errors in the log. Let me know if you need the other machine’s logs too.

Can you please provide a screenshot of the add folder section of the library? Edit: I am not seeing anything major in the logs. I didnt see the server startup logs anywhere in the zip you provided. So restarting it may not be a bad idea. I see there are 2 similar shows, might want to pull both out …

[image] Not sure about which two similar shows you are talking about. Is it one of the four that are named in the errors?

/mnt/nfs/Elements20T/TV/Laid and /mnt/nfs/Elements20T/TV/Laid (2024)

Plex Media Server Metadata & Adding Files

OK did the dance etc. The new logs are attached. Before the dance the two shows were merged in the 2024 show on Plex, now they are separate a 2011 and a 2024 show in Plex. (I fixed the folder name of the 2011 show to include the year).
