System.InvalidOperationException: No authentication handler is registered for the scheme 'You do not have permission to access this resource.'. The registered schemes are: Negotiate, Windows. Did you forget to call AddAuthentication().Add[SomeAuthHandler]("You do not have permission to access this resource.",...)?
Program.cs:
