Root Cause

• Temporary gateway system failure: The payment gateway encountered a transient technical issue

• Network connectivity issues: Communication between the merchant's system and the gateway was interrupted.

• High gateway load or maintenance: The gateway was experiencing high traffic or undergoing scheduled maintenance at the time of the request.

Troubleshooting and Solutions

• If the issue persists, recommend using an alternate payment method to complete the transaction.

• Monitor gateway status pages or notifications for known outages or maintenance events.

• Contact support@chargebee.com if repeated failures occur.

• Implement automatic retry logic with appropriate delay intervals to handle transient failures gracefully.
