XSJS Outbound call Issue: internal error code: Proxy handshake failed

Hi Experts

I was trying to write service for geocoding using Google Maps API

googleGeolocation.xshttpdest

host = "maps.googleapis.com";

port = 80;

pathPrefix = "/maps/api/geocode/json";

useProxy = true;

proxyHost = "proxy";

proxyPort = 8080;

authType = none; 

useSSL = true; 

timeout = 30000;

geolocate.xsjs

var destination_package = "crawler.mapsServices";

var destination_name = "googleGeolocation";

 

 

function geocoding(location,countryCode){

 

  try{

  var dest = $.net.http.readDestination(destination_package, destination_name);

  var client = new $.net.http.Client();

  //var req = new $.web.WebRequest($.net.http.GET,"?address=Banashankari+2nd+Stage");

  var req = new $.web.WebRequest($.net.http.GET,"?address="+location+","+countryCode+"&sensor=false&key=XXXXXXX");

  //$.response.setBody(req);

  client.request(req,dest);

  var response=client.getResponse();

  $.response.contentType = "application/json";

     $.response.setBody(response.body.asString());

     $.response.status = $.net.http.OK;

  }

  catch (e) {

        $.response.contentType = "text/plain";

        $.response.setBody(e.message);

  }

}

 

 

var location ="Banashankari 2nd Stage";

var countryCode="KAR,IN";

 

 

geocoding(location,countryCode);

I get the following message in browser

HttpClient.request: request failed. The following error occured: unable to establish connection to proxy:8080 - internal error code: Proxy handshake failed

I have successfully configured the Trust Manger I have also set the SSL in the XS Admin panel. I'm not able to overcome this issue.
