I must type my ip-address:9000 to see my app because localhost:9000 is not working.

I am not sure but could you verify if in the Grunfile.js you have this on line 69 - 72 :

    port: 9000,
    // Change this to '0.0.0.0' to access the server from outside.
    hostname: 'localhost',
    livereload: 35729

You must have the 'localhost' in the hostname if you're running your server on local.

Hope it will help.
