Why is the leet.cc app not working

[AC Question]

On my kindle fire I downloaded the leet.cc app but every time I finished doing the server name, my Minecraft name, world type, and press the button it says no internet connection even when I have full bars. I know the internet connection is working because right after that I came here and my kindle fire is not an android tablet. It's an ios.
