Accessing Web API after hosting asp.net website

Question

I have written a simple web API in the existing asp.net webforms project and published it on HostGator shared hosting.

 

API was working fine locally but not accessible after hosting.

 

Process how I created this API in My web forms project.

 

Step 1. I added a new Web API controller class to my Webform project by

             right-click on webform project ->Add->Web API Controller class.

 

Step 2 .Added some routing information to Application_Start () methof of global.asax file .

GlobalConfiguration.Configure(WebApiConfig.Register);
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { action = "GetRadarData", id = System.Web.Http.RouteParameter.Optional }
);
}
}

Step 3: Adding code to the controller class for Get method.

public IEnumerable<clsRadarInfoEnt> GetRadarData(string userId, string password)
{
string Response = "";
clsLibrary.mGetRadarList(userId, password, out RadarList, out Response);
if (RadarList == null && Response == "Invalid login")
{
var response = new HttpResponseMessage(HttpStatusCode.NotFound)
{
Content = new StringContent("User doesn't exist", System.Text.Encoding.UTF8, "text/plain"),
StatusCode = HttpStatusCode.NotFound
};
throw new HttpResponseException(response);
}
else if (RadarList == null && Response == "Incorrect password")
{
var response = new HttpResponseMessage(HttpStatusCode.Unauthorized)
{
Content = new StringContent("Incorrect Password", System.Text.Encoding.UTF8, "text/plain"),
StatusCode = HttpStatusCode.NotFound
};
throw new HttpResponseException(response);
}
else
{
return RadarList;
}
}

It was working fine locally and giving the result as aspected but after hosting the website on Hostgator showing error
