The WinRM client cannot process the request. If you do not specify an authentication mechanism or you specify Kerberos, then you cannot use "localhost" or "127.0.0.1" or "[::1]" for the remote host name.
You can explicitly specify a different authentication mechanism than Kerberos or specify the remote host as a DNS name or NetBIOS name.
