Censys Mastercard Payment Keeps Failing After a Successful Visa Payment

Hi everyone,

I previously purchased Censys Credits successfully using a Visa card. However, due to the available credit limit on that Visa card, I later switched to a Mastercard to place another order.

The Mastercard has sufficient available credit and can be used for other online purchases, but every time I try to place the Censys order, the payment fails.

Has anyone experienced a similar issue with Mastercard on Censys?

I would especially like to know:

  • Does Censys support Mastercard for Credit purchases?
  • Could the previous Visa payment or account billing history affect the new Mastercard payment?
  • Is there any additional verification or billing-address requirement for larger orders?
  • Could a failed payment attempt create a pending order that might be charged later?

Any advice or experience would be greatly appreciated. Thanks!
