ASP.NET 5 host application in IIS 8 with https bindings - asp.net

Question

Earlier I was having issue hosting ASP.NET 5 application in IIS and now I am able to host it via http. Here is my old post that contains details.
For past couple days I have been trying to enable https for my application over port 443. In launchSetting.json file I updated iisexpress settings to "applicationUrl": "https://servername:443/" with valid certificate. but I still get 404 error when I browse the application in the browser.
Here is my launchSettings.json file:
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "https://servername:443/",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"Hosting:Environment": "Development"
}
},
"web": {
"commandName": "web",
"environmentVariables": {
"Hosting:Environment": "Development"
}
}
}
}
Here is my project.json file:
"dependencies": {
"Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
"Microsoft.AspNet.Mvc.Core": "6.0.0-rc1-final",
"Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",
"Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final",
"Microsoft.Extensions.Logging.Debug": "1.0.0-rc1-final",
"Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-rc1-final",
"Microsoft.Net.Http.Server": "1.0.0-beta5",
"dnx-clr-win-x64": "1.0.0-rc1-update1",
"Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final"
},
"commands": {
"web": "Microsoft.AspNet.Server.Kestrel"
}
Startup.cs file:
public class Startup
{
// This method gets called by the runtime. Use this method to add services to the container.
// For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc() // Add MVC Dependency.
.AddJsonOptions(
opt =>
{
opt.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); // Api convert all property names to CamelCase.
}
);
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, ILoggerFactory LoggerFactory)
{
LoggerFactory.AddDebug(LogLevel.Warning);
app.UseIISPlatformHandler();
app.UseStaticFiles();
app.UseMvc(config =>
{
config.MapRoute(
name: "Default",
template: "{controller}/{action}/{id?}",
defaults: new { controller = "App", Action = "Index" }
);
}); // Use MVC from Dependency.
}
// Entry point for the application.
public static void Main(string[] args) => WebApplication.Run<Startup>(args);
}
I am not sure if it is right way to enable https in the application, but IIS bindings are configured correctly with valid certificate. So I am not sure why it is still throwing 404 error.
Any help from community is really appreciated. :)
