Autoremote direct connection to Android not work.

Other Hardware Home Automation

Hi, I searched in this forum about how-to connect Arduino and Android with Autoremote, and I found, but it not work for me, and it is very old. It's a very simple "GET".
Can anyone check the code? I'm using this one, from Arduino Tasker-Autoremote direct message:

char arserver[] = "autoremotejoaomgcd.appspot.com";


void SendMessage(){
  client.stop();
  if (client.connect(arserver, 80)){
    Serial.println("connected");
    client.print("GET /sendmessage?key=MYKEY&message=");
    client.print("something");
    client.println(" HTTP/1.1");
    client.print("Host: ");
    client.println(arserver);
    client.println("User-Agent: Arduino");
    client.println();
  } 
}

A lot of thanks for your time.
