But you haven't tested your phones on a known working server, or had someone else test your server availability from outside your network? Is the computer you're using to connect inside or outside your network?
You're letting us know you're having trouble, but you're not providing enough information to help pinpoint what the problem is.
My modded site is up and running and I can connect to it with my Android phone without issues. My other users are also not experiencing any issues.
If you want help, you have to be willing to do some simple tests that identify the problem.
It would also be helpful to know what OS and installation version you are running.
