Plex Movie / Series agent always returning "No matches found."

Plex Media Server Metadata & Adding Files
1

Server Version#: 1.40.5.8854
Player Version#: N/A

Hi everyone,

Facing a very weird issue which started on the 21st. Prior to this I had zero issues with movies matching automatically. My directory structure is:

{Movie CleanTitle} ({Release Year}) {imdb-{ImdbId}}

Tried downgrading and switching to the :plexpass Docker image but nothing seems to help.

I’ve tried several restarts but nothing seems to work out. The server is running on a dedicated Linux server on a cloud provider with a VPN in front of Plex. I haven’t had any issues with this setup for the last 2 years, they only started on the 21st.

Even shows / movies that were previously matched correctly turn up “No matches found.” now. It returns that instantly, without taking a while to search.

Is there a curl call I could maybe try from the Plex container to verify if the requests are going through?

I’ve noticed this stack trace in all my plug-in logs:

Please let me know if the whole server logs would help!

Always, its quite rare for a log except to contain the needed data.

Here you go:

From what I can see, nearly every agent log has the resourceHash exception

4

You are having network/dns issues WARN - [HttpClient/HCl#1] HTTP error requesting GET https://plex.tv/api/codecs/dca_decoder?build=linux-x86_64-standard&deviceId=6e5a4634-e661-49cc-b64f-243ad429bf92&oldestPreviousVersion=1%2E40%2E2%2E8395-c67dce28e&version=f89d5b0-6badbfebc74a8242a0378054 (6, Couldn't resolve host name) (Could not resolve host: plex.tv)

That’s incredibly weird, I ran curl on the same URL inside the Plex container and it worked just fine:

root@plex-6689968d9c-d5jwm:/# curl -i 'https://plex.tv/api/codecs/dca_decoder?build=linux-x86_64-standard&deviceId=6e5a4634-e661-49cc-b64f-243ad429bf92&oldestPreviousVersion=1%2E40%2E2%2E8395-c67dce28e&version=f89d5b0-6badbfebc74a8242a0378054'

You also had verbose logging on, You can stop plex, clear the log folder, start plex, re-create the issue and post a new copy of the logs.

Got it, here’s the new logs:

I dont know docker, but its definitely a network issue:

If I start tailing the logs, as soon as I click on Fix Match and then search I see these lines:

Aug 24, 2024 03:52:40.532 [140572083301176] DEBUG - Request: [10.42.0.130:43014 (Subnet)] GET /library/metadata/7473/matches?manual=1&title=Inside%20Out%202&agent=tv.plex.agents.movie&year=2024&language=en-US (14 live) #25dc GZIP Signed-in Token (obviyus) (MacBook-Pro.local)

It seems to execute the request correctly but there is nothing in the response. This is the case for every single piece of media in my library, even the ones that were previously automatically identified correctly.

Hmm, if I try to recreate that request:

root@plex-698dc65d4f-7zztd:~# curl -i http://127.0.0.1:39563/:/plugins/com.plexapp.system/resourceHashes
HTTP/1.1 404 Not Found
Content-Length: 0

It’s definitely hitting whatever is running on :39563 but always responding with a 404

11

404 = NOT FOUND. There’s nothing there at that hash.

12

Ah right, of course. Just thought maybe it was the issue because of the related stack trace in all the agent logs

13

Can you run PMS on the host natively ?

14

I could try. I’m hosting the server on Hetzner, do you think that could be the problem? I’ve been using a VPN within Docker so it hasn’t caused any issues so far.

15

ALL STOP!

Now it’s clear what’s happening.

Hetzner is blocked due to abuse.

All requests from Hetzner servers will return 404 or other “failure” reply.

16

Ah understood. I’ll find a different provider in that case. Thank you for your help @ChuckPa and @dbirch

If I may also recommend.

With your new provider – Use the native package.

Wrapping PMS in docker on Linux is just a layer of complication you do not need on a dedicated host
