Assets thumbnail

Dear Master,
I am trying the new version of Cockpit CMS on localhost (WSL/Debian).
Content and API are working fine. However, Assets is not showing thumbnails when I upload images to it. I checked the PHP extensions, and everything seems to be installed. Unfortunately, there are no errors in the log files. So I am in the dark.

Is there anything I missed? Please help.

Have you checked the asset database to verify that Cockpit is storing the files and remembering that they exist?

the files were uploaded, but the database is empty. the thumbs folder is also empty.

I seem to have the same problem.
Using Cockpit Pro 2.9.1. with mongolite on an Ubuntu Server.

The Thumbnails of the uploaded assets/images are not showing.
The first image is showing the preloader of the asset-thumbnails. At first it looks like it’s loading the thumbnails, but then resolves in an unknown image.


I’m also getting an error in the console for every image:

5a731f024b1a9b240b1336890da22491_70_bestFit.webp:1 
        
GET: https://**myurl**/storage/tmp/thumbs/5a731f024b1a9b240b1336890da22491_70_bestFit.webp 403 (Forbidden)

Clicking on the image to open the image in large format works and the picture is also shown.

Seems to be a problem with the .webp thumbnails.
