Dear Eskimo, Thanks for your reply. The issue was server-side. I’ve now defined a .cs class to enable CORS for all incoming requests. public static class WebApiConfig { public static void Register(HttpConfiguration config) { var cors = new EnableCorsAttribute("", "", "*"); config.EnableCors(cors); config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}", new { id = RouteParameter.Optional }); } } Thanks Mozib
