问题
I created a site using IIS, after installing .NET Hosting Bundle on server.
However, I am not able to access the site with the browser via url. Google Chrome gave the error DNS_PROBE_FINISHED_NXDOMAIN.
So,I added a binding to localhost:443, and accessed the site from the server computer. However an error appeared in the browser: HTTP 502.5. It appears that the IIS reads the http requests, as may be seen in the log.
Here is my web.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath=".\MVF2.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
</system.webServer>
</location>
</configuration>
<!--ProjectGuid: 99f7528d-8954-427a-86a5-7124668717df-->
The Program.cs file is:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Threading.Tasks;
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;
namespace MVF2
{
public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseKestrel(options =>
{
options.Listen(IPAddress.Loopback, 443, listenOptions =>
{
listenOptions.UseHttps("mycertificate.crt");
});
});
}
}
Here I show the log of the IIS site:

Next I show my Startup.cs:

services.AddMemoryCache();
services.AddSession();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app,

{
app.UseExceptionHandler("/Error.html");
if (features.DevelopmentEnvironment)
{

}
app.UseAuthentication();
app.Use(async (context, next) =>
{

throw new Exception("ERRO!");
await next();
});
app.UseSession();
app.UseMvc(routes =>
{
routes.MapRoute("Default",
"{controller=Home}/{action=Index}/{id?}");
});
app.UseFileServer();
idDbContext.CreateAdminAccount(app.ApplicationServices, Configuration).Wait();
}
}
}
Could you help me?

@salli I accessed the site via https://localhost:443/ since I had added this binding. However, besides the error in the certificate (the certificate is issued to something like *.my.me), I have an error in the launching of the app. Here I show the log of the site:

EDIT
I solved this problem enabling logging in my app web.config as following:
<aspNetCore processPath=".\MVF2.exe" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />
Then I was able to see the error in the log files in .\logs directory.
