Does anybody know why and when thumbnails for YouTube videos are shown or not? It appears to depend on the lemmy instance the posts are served from:
Without Thumbnails
With Thumbnails
Update: It’s not only YT thumbnails which aren’t shown. This is your post about the free 24 slot bag as shown on lemmy.wtf (without thumbnail), lemmy.world (without thumbnail) and feddit.de (with thumbnail):

This was fixed on
lemmy.wtfa while ago but apparently this was still an issue onlemmy.worldwhich now has been fixed:https://lemmy.world/post/1421693
The
docker-compose.ymlI copied from somewhere when setting up lemmy.world apparently was missing the external network for the pictrs container… So pictrs was working, as long as it got the images via Lemmy. Getting the images via URL didn’t work…Note: This only fixes new posts. In order to fix old posts you need to edit/save them once.
