Also, this is a good tip in general:
You can't fetch title and thumbnail for YouTube links that starts with
youtu.be. This applies not only in Lemmy, but other websites too, for example Twitter (even before Elon's era).This is, IMO due to the link doesn't really contain HTML and OpenGraph metadata. It only redirects you. If you try cURL-ing the youtu.be link, you will see that it doesn't have a response body, only some header including
Locationheader that will tell you where to redirect. The response code itself is 301.There are people on shitjustworks posting youtu.be links on !videos@lemmy.world that do have thumbnails, so whatever they're doing doesn't seem to have that problem
My .ee account has a field to put in a thumbnail URL, so other comments in this thread are kinda leading me to believe it may be a combination of instance version, and how the instance is configured
My Lemmy instance actually can't fetch YouTube thumbnail, so I actually have to put it manually lol.
See http://www.get-youtube-thumbnail.com/
Thats a super helpful site, thank you! If nothing else now I can remake my post from my .ee account and add the thumbnail manually
