Root Cause

• Internal server error at the payment gateway: The gateway's backend systems encountered an unexpected error during transaction processing.
• Temporary infrastructure issues: Server outages or degraded performance impacted transaction handling.
• High network traffic or load: Excessive transaction volumes led to system instability or failure.
• Unscheduled maintenance or deployment errors: Recent changes or updates to the system caused unforeseen issues.

Troubleshooting and Solutions

• Advise the customer to retry the transaction after some time.
• Monitor the Chargebee or payment gateway's status page for updates regarding the issue.
• Contact Chargebee Support for additional information if the problem persists or recurs frequently.
