Root Cause

• Gateway downtime: A temporary unavailability or maintenance activity at the payment gateway.
• Network disruptions: Short-term connectivity issues between systems.
• Service interruptions: Payment processor facing brief service instability.
• Timeouts or overloads: High traffic causing delayed responses or timeouts at the gateway side.

Troubleshooting and Solutions

• Inform the customer that a temporary issue prevented their payment from being processed.
• Ask the customer to retry the transaction after a short wait.
• Ask the customer to ensure they have a stable internet connection while retrying.
• Ask the customer to use an alternate payment method if the problem persists.
• Configure smart retries in your system to attempt the transaction every alternate day as per the retry_alternate_days scenario.
• Monitor the payment gateway's status dashboard (if available) for any ongoing service interruptions or maintenance notifications.
