Hey guys, first time posting here. I’m a frequent visitor on a Discourse-based forum (from page source it looks like it is 3.2.0.beta1-dev, I have no idea what the current latest version is), and I was disappointed to see that Artstation links have no preview.

This doesn’t look like a bug. If you read the error, the website is denying your access (of your server). You could try my onebox assistant plugin to see if that helps.

Getting around these restrictions needs serious experience and expertise, and I don’t have the time to learn that niche of Information Technology, so you need to rely on those who spend all day doing it: ie a proxy service.
