Job being created in database but not being processed or Queued

I am new to Hangfire but have a system ready to go into testing next week. I’ve been able to configure the Hangfire applicaton in a MVC5 web application. Hangfire will process both Recurring Jobs and Delayed jobs that will be added later. my problem, Hangfire schedules the jobs but do not move them into Enqueue. After awhile, all jobs in Enqueue stop processing and only process after restarting the application. I am using SQL Server as my storage, btw. I really need help. Thanks. Oh, I’m using Hangfire 1.4.3
