App Store Server Notifications Not Working in Production Environment Environment App Bundle ID: com.fanmuay.app Environment: Production Implementation Date: 28/01/2025 Last Successful Sandbox Test: 29/01/2025 Issue Description I'm experiencing issues with App Store Server Notifications in the production environment. The notifications work perfectly in sandbox, but they stop working completely after moving to production. What Works Server notifications are properly received in sandbox environment All purchase events successfully trigger notifications in sandbox Notification payload is correctly processed by our server in sandbox What Doesn't Work No notifications are being received from production environment No error messages are being logged Same implementation that works in sandbox yields no responses in production Questions Are there any additional configuration steps needed when moving from sandbox to production for server notifications? Is there a different certificate or authentication process required for production notifications? Is there a way to verify if our production endpoint is correctly registered? Are there any common issues that could cause notifications to work in sandbox but fail silently in production? Technical Details Our server is properly configured to receive notifications and can successfully process them in the sandbox environment. The same exact setup is used for production, but we receive no responses. We've verified our server is running and accessible. Any guidance or suggestions would be greatly appreciated. If you need any additional information, please let me know. Thank you for your help!
