Consider the following steps to rectify the problem:

Verify your billing details: Make sure all the entered information is accurate, including your card number, its expiry date, and CVV.

Switch to another form of payment: If the issue persists, consider using a different card or payment method.

Reach out to your bank: On occasion, banks may prevent transactions due to safety concerns. It would be wise to consult with them for more details.

Attempt again after some time: There might be a problem with the payment server. Pausing for a short while and retrying could potentially resolve the issue.
