Problema de conexion entre android studio y WebServices

Buenas.... Lo que pasa es que estoy desarrollando una aplicacion con Android Studio y necesito insertar los datos ingresados a mi base de datos MySQL por medio de WebServices, ubicado en mi red local, al momento de iniciar la aplicacion e ingresar los datos no me lanza ningun error, el unico error que lanza es:
