The previous topic was auto closed, so just wanted to open again in case of more suggestions to try?

Please see here for the previous details

I have also attached my latest logs with debug enabled. I censored the usernames etc.

I enabled debug log type, then attempt to play a movie and go to the chapter selection on my samsung S22.
The logs show repeating errors for the thumbnail GET commands.

May 24, 2024 21:29:18.135 [22847804537656] WARN - [HttpClient/HCl#8d6] HTTP error requesting GET https://plex.censoredmydomain.com:443/library/media/154035/chapterImages/1?X-Plex-Token=xxxxxxxxxxxxxxxxxxxx (7, Couldn’t connect to server) (Failed to connect to plex.censoredmydomain.com port 443 after 17 ms: Couldn’t connect to server)

But the thumbnail for the same movies displays correctly on the plex web via the same wifi connection (external network from the server).
Plex Media Server.log (458.6 KB)

I use traefik 3.0 to control access remote access to the server but using web client or apple client to my server allows chapter thumbnail to show. So i dont believe it is the traefik setup being an issue.

I have the exact same issue with the chapter thumbnails:

  • They work remotely on all platforms
  • They work locally on web and tizen
  • They don’t work locally on Android/Android TV

My setup:

  • Plex on Docker (Bridge Network 172.X.X.X)
  • Settings > Network > Custom server access URL set to host IP (http://192.168.1.X:32400)

Looking at the android debug logs I couldn’t see any failed chapter image request.

But after troubleshooting, I think I identified the issue.
It seems that for chapter thumbnails (not sure if for anything else as well) the android client does not use the custom server access URL.

This means that instead of using either:

the android client seems to always use the detected plex IP, which in this case will be the internal container IP, which is not accessible (172.X.X.X).
And thus the thumbnails won’t work for docker setups using bridge networking and possibly won’t work for other setups either if allow insure connections is set to never.

To validate this, I created a firewall rule to route all traffic from 172.X.X.X:32400 → 192.168.1.X:32400, which, after making sure insecure local connections were allowed, allowed the chapter thumbnails to work.

@morganj I think what the android client should be doing is using the same hostname being used for the video stream also for the thumbnails.
Is this a known issue that can be looked at?

Great find! :+1:

For me I don’t get thumbnails on android client local or remote.

I have my plex on a docker container with Traefik providing the domain name forward via the docker network for ecternal access vis port 443. I also have direct local ip access to the container using the container port mapping.

Thanks for the extra info, I will create an issue and get someone to look into this.
