CORS in .net Core application isn't working

Question

I have .Net Core application with angular 2 cli. I am trying to call my controller action from the different port, I know that I can use CORS to make that work, but it is not working. has anyone the idea what could be the problem? thank you!

Your current configuration is allowing the wrong origin (HTTPS and not HTTP).

//Optional - called before the Configure method by the runtime
public void ConfigureServices(IServiceCollection services)
{
    services.AddCors();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{    
    app.UseCors(builder =>
       {
           builder.WithOrigins("http://localhost:4200")
           .AllowAnyMethod()
           .AllowAnyHeader();
       });
   )
}
