Says my credit card security is invalid

Hey im trying to activate two factor authentication on my phone, but when doing so I have to confirm my payment method. When im trying to confirm it it keeps saying the security code is wrong but i know that its not wrong and ive triple checked. When activating apple pay for example I wrote the same code and there it worked.

I did try both in the phone directly but also on the website, but it keeps saying wrong code, anyone having similar issues and what can I do to fix it?
