Root Cause

• Payment gateway experiencing temporary downtime: The payment processing system is currently unable to handle transactions due to internal errors or overload.

• High transaction volume: The gateway is processing an unusually high number of requests, leading to intermittent failures.

• Backend service disruption: One or more supporting services critical for transaction processing are temporarily unavailable.

• Scheduled or unscheduled maintenance: Maintenance activities are affecting transaction processing capabilities.

Troubleshooting and Solutions

• Advise customers to retry the transaction after a brief waiting period.

• Suggest using an alternate payment method if the issue is urgent.

• Monitor the payment gateway's status page or incident reports for updates on resolution.

• Contact the payment gateway support team if the issue persists longer than expected or occurs frequently.
