a Remote Webcam using NodeJS, Android, Opera Mobile, Web Sockets and HTML5 websocket is not working

I've a problem with code that I was got from here

I've installed web socket from npm successfully. but the websocket is not working. this is a warning from firebug console :

Firefox can't establish a connection to the server at ws://192.168.137.133:8000/.


var ws = new WebSocket("ws://192.168.137.133:8000/"), 

error on :

client.js (line 11)

FYI

myserver IP is : 192.168.137.1
and my phone IP is : 192.168.137.133

Thanks for your answer masters. Cheers!!! :D
