Getting error on creating web service reference New-WebServiceProxy : The HTML document does not contain Web service discovery information

I'm getting the same error message. seems a few different scripts out there point to the same webproxy but they fail:
New-WebServiceProxy : The underlying connection was closed: The connection was closed unexpectedly.
At C:\scripts\whois3.ps1:43 char:16

• ... f ($whois = New-WebServiceProxy -uri "http://www.webservicex.net/whoi ...

•             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  

  • CategoryInfo : ObjectNotFound: (http://www.webs...whois.asmx?WSDL:Uri) [New-WebServiceProxy], WebException
  • FullyQualifiedErrorId : WebException,Microsoft.PowerShell.Commands.NewWebServiceProxy

Ideas?
