Twitter card IMAGE not loading - different domain from approved Twitter Card domain

#1

Hello - We got quick approval for our Twitter Card. However, using both the Validator tool and posting from my own account, the image isn’t loading as expected with the card. Our primary *.metopera.org domain was approved for the summary_large_image card, but the images themselves are currently hosted and served from a different domain. Should this matter? What else might be preventing the image from appearing in the card? Thanks.

The location of the image shouldn’t matter, and it looks like the robots.txt on http://link.metoperafamily.org:90/Video_ipadstills/811357011799_768x432.jpg is valid.

I do wonder if the :90 protocol is throwing something off. I would try playing with that.

Occasionally, one of the following might be helpful:
