title: Hangfire dashboard returns 404
body: <p>When trying to access the hangfire dashboard on my local IIS at domain/hangfire/ I get a 404 response. This is in a webforms project targeting .Net 4.5.1, Hangfire is version 1.5.3. My startup and authorisationoverride classes are as follows:</p>
  
  <pre><code>[assembly: OwinStartup(typeof(MyNamespace.Startup))]
  namespace MyNamespace
  {
      public class Startup
      {
          public void Configuration(IAppBuilder app)
          {
              GlobalConfiguration.Configuration.UseSqlServerStorage("MyConnString");
  
              DashboardOptions opts = new DashboardOptions
              {
                  AuthorizationFilters = new[] { new AuthorisationOverride() }
              };
  
              app.UseHangfireServer();
              app.UseHangfireDashboard("/hangfire", opts);
          }
      }
  }
  
  public class AuthorisationOverride : Hangfire.Dashboard.IAuthorizationFilter
  {
      public bool Authorize(IDictionary&lt;string, object&gt; owinEnvironment)
      {
          return true;
      }
  }
  </code></pre>
  
  <p>Jobs are running successfully, but I've run out of ideas for getting the Dashboard to work.</p>
