I see the same problem on the official nextcloud:27 docker image. When scrolling down in the "Photos" page it properly loads a few hundred photos; then, in the middle of loading, I get a ton of 500 server errors. Where it fails it shows the filename instead of the thumbnail. I checked the filesystem transition between photos that load properly and photos that don't and they're in the same directory with the same permissions (this is on an external photos location). It looks like an out of memory or buffer overrun situation but there's very little feedback from the loading software.

Hi @derritter88 (and @spikeygg): Thanks for helping making Photos (and Nextcloud) better with your feedback reports.

Can you reproduce provide the associated raw log entries from your server-side nextcloud.log when this occurs (or equivalent: from Admin->Logging and moving the cursor to the right of a log entry and clicking "Copy Raw")? That will provide some clue as to what conditions are creating this behavior in your environments.

Hello @joshtrichards! Unfortunately the Nextcloud log is empty.

But what is a bit interessting to me (not sure if this is relevant for this ticket): In general my webserver (Apache2) is using http/2.
Any thumbnails via browser is being displayed as http/1.1+h2

Is this a feature or a bug?
