I have this problem too, but i`m getting the logo of "Moana" movie (see attached).
But because i`m from Israel i tried to connect trough US vpn, and then i got the correct image (see attached).
So i think there is a problem with the IP location when trying to use with your api.
Can you please check this and fix?
When using "https://" with the link i`m getting the correct image from my regular location connection
Here is another topic with the same problem:
