Realms is not saving card info and not allowing the extending of realm

From the "Wallet & Realms" page. Realms is not saving card info and not allowing the extending/reactivation of my realm. It says:

"ERROR

Oops! Something went wrong and we could not validate your cart.

Request ID: f32c544654a35420"

Already tried it on two different days and restarting my computer and doing it on different devices.
