NullReferenceException for injected service in RecurringJob

Hangfire has been working perfectly for over a year now. I recently refactored into services using Ninject for dependency injection. Now my recurring tasks throw an exception, saying that the service is null. If I AddorUpdate the recurring jobs again, and trigger them manually from within the Hangfire dashboard, they work fine.

No null exceptions when they are fired on local though…

Any suggestions?
