After we got attacked we tightened security. But then our images were not loading on Facebook and Twitter feeds.
Facebook got fixed by adding IP Access Rules AS63293 and AS32934 and is now working fine.
But we cannot get Twitter Card images to work. When i run the card URL ( 0ullrrYNHV or tJpikIjp8X ) through the twitter card validator, it says “Unable to render Card preview”.
I have been trying to fix this for many hours. Anyone have any suggestions? Greatly appreciate any help you can provide!
