Hangfire background jobs stops sending notification

Hi,

Could anyone help me why hangfire stops sending Notifications?
I have two server running UAT and Prod.
Hangfire works just fine in UAT but when I deploy it to Prod there's no
notification saved.

Does anyone know about this problem?

Start with the Hangfire deployment configuration and runtime logs for the UAT and Prod servers, focusing on why notifications are not saved in Prod. Reproduce the deployment difference and identify a concrete failure or configuration mismatch before defining a testable fix; done means notifications are saved reliably in Prod as they are in UAT.
