Unable to parse warning while using wsimport

I am trying to generate proxy code from webservice using wsimport command from an wsdl,

C:windowssystem32>"%JAVA_HOME%binwsimport" -keep -verbose "path_to_wsdl.xml"

getting the following warning..

[ERROR]         Unable to parse "https://xxxxx/url_to_webservice.svc?wsdl=wsdl0" : java.security.cert.CertificateEx
ception: No subject alternative DNS name matching xxxxxxx found.

wsdl:

<wsdl:import namespace="urn:xxx" location="https://xxxx:port/url_to_service.svc?wsdl=wsdl0" />

Is there error related to wsimport parsing? please help on it. Thanks in advance.
