casperjs doesn't work as expected on windows machine

I have a casperjs script which gives the desired result when I run on a linux server, but when I run the same from my laptop, it doesn't work.

How should I debug? Logs of the working one:

Script:

var casper = require('casper').create ({
  waitTimeout: 60000,
  stepTimeout: 60000,
  verbose: true,
  logLevel: "debug",
  viewportSize: {
    width: 1366,
    height: 768
  },
  pageSettings: {
    "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0",
    "loadImages": true,
    "loadPlugins": true,
    "webSecurityEnabled": false,
    "ignoreSslErrors": true
  },
  onWaitTimeout: function() {
    casper.echo('Wait TimeOut Occured');
  },
  onStepTimeout: function() {
    casper.echo('Step TimeOut Occured');
  }
});

casper.start('http://caspertest.grsrv.com/', function() {
    this.fillSelectors('form', {
        'input[id="userName"]': 'test',
        'input[id="userPassword"]': 'test',
    }, false);
    this.capture('ss.png');
    this.click('input[id="loginButton"]')
});


casper.waitForSelector('#aggr_actionAccept', function() {
    this.click('input[id="aggr_actionAccept"]')
});

This is how I am executing:

casperjs --ignore-ssl-errors=true test.js

The resource is with a client and I am using a VPN on my windows machine to access the resource on my browser. The linux machine on which it is working is with the client itself

Add a resource.error event handler:
casper.on("resource.error", function(resourceError){
    console.log('Unable to load resource (#' + resourceError.id + 'URL:' + resourceError.url + ')');
    console.log('Error code: ' + resourceError.errorCode + '. Description: ' + resourceError.errorString);
});
It seems, this is a known PhantomJS bug (Fixed in 2.5 beta).
You can download PhantomJS 2.5 beta from this page.

You need to add the following callbacks, to catch all the errors:

casper
.on("error", function(msg){ this.echo("error: " + msg, "ERROR") })
.on("page.error", function(msg, trace){ this.echo("Page Error: " + msg, "ERROR") })
.on("remote.message", function(msg){ this.echo("Info: " + msg, "INFO") });
