Reproduction steps

create a folder (pics) containing a single image file (abc.jpg)

1. import [external library](https://immich.app/docs/features/libraries#external-libraries), say pics
2. create external library via user->account settings->libraries->create external library
3. view the album (pics), verify the image is present (abc.jpg)
4. update `abc.jpg` with a new file `def.jpg` (`cp def.jpg abc.jpg`)
5. refresh the external library. user->account settings->libraries->`pics` external library->`force re-scan all library files`
6. observe the server logs to ensure the process has completed (shouldnt take more than a few seconds)
7. view the album again.
Issue: 
1/ instead of seeing `def.jpg` metadata, I still see `abc.jpg` metadata
2/ instead of seeing `def.jpg`, I still see `abc.jpg`
deeper dive: on downloading the image, I see the correct image `def.jpg`.
possible bug: the thumbnail is not updated on step 5. :(

Additional information

I see following AssetService errors

Commenting to follow. I too am not being able to see the thumbnails
image

Nor am I being able to see the actual image/faces
image

When looking at my files, I see:

I don't think it's a permission issue, as my files look like this:

I've also tried the solution in #4246 to regenerate the missing thumbnails job, but nothing changed.

Seeing the same issue as OP. I rotated a bunch of photos, did a rescan, thumbnails stay the same, but if I download the file, it is accurate. Running v1.99.0.

@figadore commented on GitHub (Jun 5, 2024):

Possibly related, I restored my database, which caused all assets to be listed as "Offline" until I force-rescanned. Now everything works except the faces at /people. It works when I manually go into a person and "Select featured photo", but I can't do this for all 400 detected people/faces. How do I get it to regenerate the person thumbnails?

This is a current limitation of the external libraries feature. Basically, checksum is emulated and the browser cache bust requires a checksum change. We may move this to be nonce-based in the future.
