The "Do Not Honor" authorization or declined transaction error can occur when you're trying to pay using a debit or credit card.
This error usually happens because your bank is rejecting the transaction request for one of the following reasons:
The card has expired.
The card details you provided are incorrect.
Online transactions are restricted for that particular card.
If you're trying to make a purchase in a different country than where your card was issued.
Since the specific reason can vary, the best course of action is to contact your bank directly. They will be able to inform you of the exact reason for the error and guide you on the necessary steps to resolve it.
Alternatively, you can try using a different payment method.
