Configuration of Ejabberd in Amazon (AWS) issue

I am trying to configure Ejabberd on AWS .
Created new instance of 4GB RAM and install ejabberd through ubuntu. Also i started server and checked its status and it showing server started with private ip address . ( Name with private ip address is showing on server status command)

When i checked that private ip in my AWS , i found it is there in private ip , but whenever i try to open Ejabberd web admin by url : ip/.admin/5280 then it dint open .

I also put my question on StackOverflow.com : http://stackoverflow.com/q/41423506/3400991

Kindly help . I am very keen to create a chat application in iOS app.
