Xampp, internet time, php hosting [Help Needed Urgent Please]

Hi im creating a simple unity game.
I’m implementing Internet time to stop players from cheating. SO far i have installed Xampp and started hosting a php file locally. works excellent on unity editor on pc but when i install apk on mobile, nothing happens.

What am i doing wron? please someone put me in the right direction.

I have a feeling that if you want to use the “apk” file, you should use Unity 5 Remote

because if it’s an APK file on your Android phone then obviously your phone can’t find the server from your computer.
You could also check out Free SQL Database in order to test your game on an Android device.
