Root Cause

• Generic processing failure: The payment gateway encountered an unspecified error during the transaction.

• Temporary technical issues: Momentary service interruptions or network problems affected the transaction flow.

• Invalid or incomplete payment information: Missing or incorrectly entered payment details caused the transaction to fail.

Troubleshooting and Solutions

• Advise the customer to retry the transaction after some time, as the issue may be temporary.

• Recommend using a different payment method if the issue persists.

• Ensure that all required payment details are entered correctly and completely.

• Contact the payment gateway support team for detailed diagnostics if failures continue.

• Suggest the customer contact their bank to understand the reason for the decline and resolve any account restrictions.
