Hello,

I recently added funds to my Steam account, and the Community Market has prompted me to verify my payment methods. However, I’m encountering issues with verifying my Mastercard. Each time I try, I receive the following message:
"Your bank has declined one or both of the authorizations. Please resolve this issue with your bank and try again."

I contacted my bank, and they informed me that they are unable to assist as the issue appears to involve an unsecured process on their end.

Could you please advise me on how to proceed to resolve this? Or did somebody have the same problem?
