process the request. The following error with errorcode 0x80090311 occurred while using Kerberos authentication: The
are currently no logon servers available to service the logon request.
 Possible causes are:
  -The user name or password specified are invalid.

  -Kerberos accepts domain user names, but not local user names.
  -The Service Principal Name (SPN) for the remote computer name and port does not exist.

 After checking for the above issues, try the following:
  -Check the Event Viewer for events related to authentication.

use HTTPS transport.
 Note that computers in the TrustedHosts list might not be authenticated.
   -For more information about WinRM configuration, run the following command: winrm help config. For more
