.NET Core gives unknown error while processing HTTPS certificate [closed]

Question

I'm trying to build a .NET Core server that uses a HTTPS connection.

I created a self-signed certificate using dotnet dev-certs tool and set up Kestrel like this:

    return WebHost.CreateDefaultBuilder(args)
                    .UseKestrel(options =>
                    {
                        options.Listen(IPAddress.Loopback, 5000, lisOpt => lisOpt.UseHttps("myCert.pfx", "test"));
                    })
                  .UseStartup<Startup>()
                .Build();

But when I try to connect to it with my client, I keep getting this exception:

fail: Microsoft.AspNetCore.Server.Kestrel[0]
      Uncaught exception from the OnConnectionAsync method of an IConnectionAdapter.
System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception. ---> System.ComponentModel.Win32Exception: An unknown error occurred while processing the certificate

What am I doing wrong?

Answer 1

This apparently happened because my client sent requests to 127.0.0.1 instead of 'localhost'.
