Hi, trying to setup a server myself. Following the instructions from join lemmy it seems pretty doable on docker on my vps. What drives me crazy though is the thumbnail behavior. External images show thumbnails, but images uploaded to my server just show the link arrow in the thumbnail view. When i look at my browser devtools it just shows the rounded thumbnail icon. Is this expected behavior or not? If not, anyone can give guidance on checks to perform for thumbnail creation for uploaded images?

Thx, flutser
