The card issuer has determined the payment amount is either too high or too low. NMI has returned the error code mostly for credit cards (for example, the card reached the credit limit). However, sometimes the issuer bank can indicate the error for debit or prepaid cards (for example, card has insufficient funds).
The customer will need to contact the issuing bank for more information on the card's limit restriction or try another method of payment.
Contact the customer to have them add a new payment method and add it to their Scheduled Order.
Once a new payment method is added to the Scheduled Order, the Scheduled Order should be processed with the new payment method.
Once this issue is resolved, you should use the action to Restart Processing the Failed Scheduled Order.
