Tried running it from local host but in cmd prompt its fine as i see "Quit the server with CTRL-BREAK.". But not connecting in browser. Also tried telnet to connect to that port, but failed. what could be the reason? can't be a proxy as even telnet is not workiing

Add the port number, probably 8000, after the url in the browser: http://127.0.0.1:8000.
