Ionic serve does not load angular js and ionic css

I am new in this Ionic field. I created a new app in my localhost folder(C:\xampp\htdocs). When I go to "http://localhost/ionapp/www/" everything works fine but when I run the app from "ionic serve" command I get the blank page. When I viewed the page source I found that ionic.css and ionic.bundle.js file are not loaded during ionic serve. And in the console I get the error like "angular is not defined". Can anyone please help me fix this?

Here is my index.html which should load css and js files

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <title></title>

    <link href="lib/ionic/css/ionic.css" rel="stylesheet">
    <link href="css/style.css" rel="stylesheet">

    <!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
    <link href="css/ionic.app.css" rel="stylesheet">
    -->

    <!-- ionic/angularjs js -->
    <script src="lib/ionic/js/ionic.bundle.js"></script>

    <!-- cordova script (this will be a 404 during development) -->
    <script src="cordova.js"></script>

    <!-- your app's js -->
    <script src="js/app.js"></script>
    <script src="js/controllers.js"></script>
    <script src="js/services.js"></script>
  </head>
  <body ng-app="starter">
    <!--
      The nav bar that will be updated as we navigate between views.
    -->
    <ion-nav-bar class="bar-stable">
      <ion-nav-back-button>
      </ion-nav-back-button>
    </ion-nav-bar>
    <!--
      The views will be rendered in the <ion-nav-view> directive below
      Templates are in the /templates folder (but you could also
      have templates inline in this html file if you'd like).
    -->
    <ion-nav-view></ion-nav-view>
  </body>
</html>

So it was not the issue with my ionic but with my browser. Turns out I was getting ERR_CONNECTION_RESET in my console. So basically what I did was

  1. Open cmd prompt as administrator.
  2. Run the command netsh winsock reset.
  3. Restart my computer.

I don't know how it happened but it solved all my problems.
