Mobile automation problem

I use new Mobile automation feature, but i cant connect to my device.
I have error like
RemoteException wrapping OpenQA.Selenium.WebDriverException: Unexpected error. System.Net.WebException: Unable to connect to the remote server —> System.Net.Sockets.SocketException: Подключение не установлено, т.к. конечный компьютер отверг запрос на подключение 192.168.0.104:80
