Plex don't trust what it cached

Plex Media Server

Hi Everyone,
I have faced some issues with posters and backgrounds lately. It doesn’t apply any and they remain black after I chose desired image. After that this image looks like transparent rectangle.
In the logs I can see following records:

Apr 20, 2022 15:40:12.041 [0x7f5ef19f2b38] ERROR - Error resizing an image, we don't trust what we cached [/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Cache/PhotoTranscoder/7a/7abeba73c4ccfd1ea6d4df8efbf022d724b7ab1c.jpg]

Can someone advise how to fix this?

Something has probably mucked up the permissions in there or the file system is/was full.

Not trusting means the size is likely 0 bytes. (indicator of permissions problem/free space at time of creation).

If you’re still running with a stock config:

sudo chown -R  plex:plex /var/lib/plexmediaserver

Then restart Plex and have it refresh all the metadata.

If that doesn’t resolve it, Download the logs ZIP file and we’ll take a look

Thank you, @ChuckPa .
System was not full - df -h shows more than 30GB free space
Permissions were also fine. plex:plex is the owner.

However I managed to resolve this. It appeared that TMDB has blocked access to their resources from the place, where I’m located.

Routing the traffic to TMDB through Europe tunnel solved this issue for me.

Thanks and sorry for bothering.

@dmdrl

Those errors aren’t impacting operation.

I don’t see them very often but when I do, it’s usually because I upgraded the media (better quality) and forgot to have PMS “Analyze” the file again. (the file is newer than the last time analyzed)

I wouldn’t worry about these errors but if you want it perfect,
Select all the media items in Plex/web. → Analyze
Let it walk through all the media and update the analysis (might take some time)

What’s happening is

Thanks @ChuckPa
Will do, I noticed that those errors related to the files I still have black posters with. Unfortunately, I fixed dozens of items manually, the rest are still black.

For those which have no posters, I would start getting more drastic.

  1. Move the file out from where it can be monitored
  2. Scan Files
  3. Empty Trash
  4. Clean Bundles
  5. Optimize the database
    – this really makes PMS forget it ever saw it

Now make certain the naming is 100% correct (fixing naming after it’s scanned almost never works right)

  1. Move the file back
  2. Scan files again and let it pull it down again.

If not, show me please what’s happening (Download the logs immediately after it’s all done scanning and pulling metadata)

Do this for one file. Confirm it resolves the problem before doing any others
