Hello!
While putting together new edh deck I've noticed that none of the card images are showing at all.
When I hovered over any card in text mode the only thing that showed up was that error message:
When I tried to print proxies same thing happened, all images were broken, but at least printing text proxies works.
I've tested many different
web browsers: Firefox, Google Chrome, Microsoft Edge, Brave and the results were the same each time.
