Open Graph iMessage og:image with Signed S3 Urls

I am generating link previews with Open Graph specification and my server is returning a meta tag og:image with an image that is a shortlived signed S3 url.

This signed URL works in every other platform that supports open graph however iMessage does not display the image. Is there documentation on why it would or would not support a long signed url?
