Getting Unable to read WSDL error in coldfusion, please help

I’m trying to invoke a webservice using cfinvoke which is as follows:

<cfinvoke
webservice="https://xyz/infoLookup.php?wsdl"
method="infoLookup"

returnVariable="info">
<cfinvokeargument name="phoneNumber" value="7182973186"/>
<cfinvokeargument name="userName" value="12345"/>
<cfinvokeargument name="password" value="password"/>
</cfinvoke>

<cfdump var="#info#">

And here is a part of the message name from the WSDL :

<message name="infoLookupRequest">
  <part name="phoneNumber" type="xsd:string" />
  <part name="userName" type="xsd:string" />
  <part name="password" type="xsd:string" />
  </message>

And here is a part of Operation name from WSDL:

<portType name="vtsInfoLookupPortType">
- <operation name="infoLookup">
  <documentation>Get phone number information.</documentation>
  <input message="tns:infoLookupRequest" />
  <output message="tns:infoLookupResponse" />
  </operation>
  </portType>

I’m getting the following error:

Unable to read WSDL from URL: https://xyz/infoLookup.php?wsdl.
Error: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated.

The error occurred in C:\XYZ\A\Soap\soapreq.cfm: line 37

35 : <cfinvokeargument name="phoneNumber" value="7182973186"/>
36 : <cfinvokeargument name="userName" value="12345"/>
37 : <cfinvokeargument name="password" value="password"/>
38 : </cfinvoke>
39 :

Please let me know if I’m doing something wrong

Thanks
