Hi everyone, I’m trying to solve an issue with missing images. What’s the problem We have a category with posts that contain video URLs (PeerTube instance). The JSON contained "image_url" : .... We switched to another PeerTube instance and replaced all the old URLs in the posts with the new ones. The preview is shown, and everything looks okay; however, in the category JSON file → "image_url" : null. What I’ve tried I went through the settings I searched online and also here; however, I found nothing useful for our case (also old - May 2020; this happened suddenly, so I suspect it’s on our side) rebuild html for posts didn’t help either Questions How does Discourse actually extract thumbnails from these services? From what I’ve been able to find, it should be automatic. Are there any settings I missed? Do we have to do something on the PeerTube instance (is there some setting like “allow thumbnail scraping” or something like this? IDK PeerTube, just spitballing here) Info I have admin access to the forum Discourse 3.5.0.beta4-dev We are using Cloudflare Thank you for any help or pointers you can give me.

We have found the problem. It was highly likely due to a custom plugin that extracted the thumbnail, but it has stopped working. Sorry for the long useless post. (I can’t edit my own posts because … reasons.)

That’s my guess.
