I can see the image here, FYI.
Do you copy images to a CDN? I do. Sometimes that causes an image to not show for me as I’ve cached the original one (or something). It normally works out after a few minutes.
If you do copy media over, check all your options to make sure it is still working (like uploading images); if you don’t copy media over, maybe that domain is blocking your embed.
Just some ideas.
