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?
