ASP.Net MVC and 51Degrees - Device Detection Issue

The code below works locally but not when hosted on the server (Win 2016). Any ideas?

public abstract class BaseController : Controller {

    protected override void Initialize(System.Web.Routing.RequestContext requestContext)
    {
        base.Initialize(requestContext);


        Session["DeviceInfo"] = new Device();

        if (WebProvider.ActiveProvider != null)
        {
            if ((requestContext.HttpContext.Request.Headers != null) && (requestContext.HttpContext.Request.Headers.Count > 0) && (requestContext.HttpContext.Request.Headers.HasKeys()))
            {
                // Perform device detection on the headers provided in the
                // request.
                var match = WebProvider.ActiveProvider.Match(
                requestContext.HttpContext.Request.Headers);

                Session["DeviceInfo"] = new Device(match);
            }
        }
    }

I'm not sure what scenario would cause the Request.Headers collection to be null, but I would assume it must be something to do with the hosting configuration / environment.

I would suggest stripping it back to a very basic 'hello world' style web page that just displays the names and values of any headers. If that doesn't work then you've definitely got a configuration/environment issue. If it does then you can start adding bits in until you find what is causing the problem.
