For a3l.netlify.app / alll.blog :
I have images hosted here such as https://alll.blog/a/ai-penny-drop-hero.D2bsDQq6.jpg.
They can be reached by a browser and Apple messages, but not by X, Linkedin, Facebook, as tested by pasting these images directly in as a post. Additionally the og:image tag containing the same URL is not found, but again, this is not misconfiguration, directly pasting the image url into the posts renders “Page not found”.
The exact same image file uploaded to Cloudinary and served does show up when pasting it’s URL into the post.
What could this possibly be? Deep searching with AI has not helped
