I want to create a site with a certificate I use this to generate a certificate:

static byte[] MakeCert()
  {
      var ecdsa = ECDsa.Create(); // generate asymmetric key pair            
      var req = new CertificateRequest("cn=foobar", ecdsa, HashAlgorithmName.SHA256);
      var cert = req.CreateSelfSigned(DateTimeOffset.Now, DateTimeOffset.Now.AddYears(20));

      //// Create PFX (PKCS #12) with private key
      File.WriteAllBytes($"{path}\mycert.pfx", cert.Export(X509ContentType.Pfx, "123456"));
      return cert.Export(X509ContentType.Cert);      
  }

Then I call here:

..
    var certBytes = MakeCert();
    store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
    store.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadWrite);
    X509Certificate2 certificate = new X509Certificate2(certBytes, (string)null,
        X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet);
    store.Add(certificate);
    web.CommitChanges();                                                                        
    var site = web.Sites.Add(appName, "http", $"*:{webPort}:{appName}", appDir);
    site.ServerAutoStart = true;
    var binding = site.Bindings.Add($"*:{sslPort}:{appName}", certificate.GetCertHash(), store.Name);
    binding.Protocol = "https";                                        
    site.ApplicationDefaults.ApplicationPoolName = appPoolName;
    web.CommitChanges();
    store.Close();
    store.Dispose();
    return true;
}
catch (Exception ex)
{
    MessageBox.Show($"An error occurred when creating IIS App: {ex.Message}", "Error");
    return false;
}

But I get the error:

value does not fall within the expected range.

How to correct this?
