This card cannot be used on this website/app. Please try another card

Greetings. I'm trying to make a donation but when I select credit card and enter the info it marks "This card cannot be used on this website/app. Please try another card" .

Now I know for a fact that nothing is wrong with my credit card as i use it almost everyday for all kinds of payments. and it is not a prepaid card. Is anyone else getting this error and is there a way to solve it so I can make the donation with the same card?
