The issue you are facing:
When sharing an image with the /preview URL, no size is being sent in the response anymore.
I cant even tell when this has started to happen, tbh. Here is an example link to see for yourself: https://cloud.cynthialabs.net/s/gSN43LgX6iKBxNX/preview. The reason I even noticed is because I use ShareX to upload images to my cloud and then embed these on Discord, which now just fails after over a year of using it like that. I barely touch the server anymore, because I don’t want to mess with a well-running system. So there’s no tampering that could have caused this. I also don’t believe it was an app-update as the last one done was about a week ago (caught me there, I’m a bit late)
Here is an image, from a different Cloud I do not own, that embeds just fine: https://cloud.disroot.org/s/RSZgiiS4AmpicEF/preview
Is this the first time you’ve seen this error? (Y/N):
Y
Steps to replicate it:

The output of your Nextcloud log in Admin > Logging:
Clear. No errors
The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

The output of your Apache/nginx/system log in /var/log/____:
Just like admin logs, no errors indicating such an issue.
Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

when a preview is accessed
The same goes for every media on discord. My Clouds logo doesnt embed anymore either. I can bypass it with using /download/filename.png however that’s just an ugly URL
Any help would be greatly appreciated.
