Iis error 500 to Get /HangFire

Dear, I implemented HangFire in my asp.net webForms.
In development works very well. However, when publishing IIS IIS the following error appears:

JobStorage.Current property value has not been initialized. You must set it before using Hangfire Client or Server API.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I using:

class Startup (OwinStartup)
class HangfireBootstrapper : IRegisteredObject
class ApplicationPreload : System.Web.Hosting.IProcessHostPreloadClient

Any idea what I did wrong?
Thank you

We started seeing this just today for the restore command in our Azure DevOps pipelines, we have been unable to track down why this started failing
