AS3 socket cannot load data from - actionscript-3

Question

I have searched internet for a lot of times but could not find any clue. I am using sockets to connect to socket server. (Also we tryed different socket policy files, but none worked)
private var SERVER_URL : String = "http://192.168.0.105";
private var PORT_NUMBER : int = 1435;
private var _socket : Socket;
// signal
private var _signal : Signal;
public function BackendService()
{
// nastavenie socketu
_socket = new Socket();
_socket.addEventListener(Event.CONNECT, connectHandler);
_socket.addEventListener(Event.CLOSE, closeHandler);
_socket.addEventListener(ErrorEvent.ERROR, errorHandler);
_socket.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
_socket.addEventListener(ProgressEvent.SOCKET_DATA, HandleMsgFromServer); // ak pride sprava zo serveru
Security.allowDomain("*");
Security.allowInsecureDomain("*");
Security.loadPolicyFile("http://192.168.0.105:8000/crossdomain.xml");
// signal na dispatchovanie eventov
_signal = new Signal();
connect(); // I am doing it from other class, but for sake of example, I am calling from here
}
public function connect():void
{
_socket.connect(SERVER_URL, PORT_NUMBER);
}
My crossdomain - socket policy file are sitting on port 8000 and looks like this:
<cross-domain-policy>
<site-control permitted-cross-domain-policies="master-only"/>
<allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>
I am getting this error:
Error #2044: Unhandled securityError:. text=Error #2048: Security
sandbox violation:
file:///C:/projects/TennisHeroes/bin/TennisHeroes.swf cannot load data
from http://192.168.0.105:1435.
Thank you very much for any advice!
