Verbindung zum Socket kann nicht hergestellt werden?

var ws = new WebSocket("ws://77.21.24.70:20132");		ws.onopen = function()		{			// Web Socket is connected, send data using send()			ws.send("Message to send");			alert("Message is sent...");		};		ws.onmessage = function (evt) 		{ 			var received_msg = evt.data;			alert("Message is received...");		};		ws.onclose = function()		{ 			// websocket is closed.			alert("Connection is closed..."); 		};
