Root Cause

• Temporary gateway processing issues: The payment processor experiences momentary disruptions affecting transaction submissions.
• Invalid or incomplete submission payload: Data required for processing is missing or incorrectly structured.
• Timeouts or transmission errors: Network delays or interruptions during transaction submission.
• System maintenance: The payment gateway is undergoing scheduled maintenance, affecting transaction processing.

Troubleshooting and Solutions

• Inform the customer that there was a temporary problem submitting their transaction.
• Ask the customer to retry submitting the transaction after a few minutes.
• Ask the customer to ensure that all required information is correctly filled in before resubmitting.
• Monitor the gateway's service status page for any reported disruptions or maintenance activities.
• Review system logs if invalid payloads are suspected.
• Implement a standard retry mechanism to resubmit affected transactions automatically where applicable.
