Android Xmppconnection with prosody server

Question

I am able to connect with my local server (prosody) but when i am trying to connect hosted server, i am unable to connect .

Here is my connection request

  XMPPTCPConnectionConfiguration.XMPPTCPConnectionConfigurationBuilder builder =
            XMPPTCPConnectionConfiguration.builder();

    builder.setServiceName("my_service_name");
    builder.setHost("xx.xx.xxx.xxx"); // my host name
    builder.setPort(5281); // myport name (i have used 5281 for https as per the prosody docs )
    builder.setUsernameAndPassword(mUsername, mPassword);
    builder.setRosterLoadedAtLogin(true);
    builder.setResource("Rooster");

    mConnection = new XMPPTCPConnection(builder.build());
    mConnection.addConnectionListener(this);
    mConnection.connect();
    mConnection.login();

When i am trying to connect , i am getting XmppPullparser exception as shown below , please help me.
