WebSocketException: Failed to get the input stream of the raw socket: Handshake failed

I am getting exception while connecting to secure web socket

This is Server code...

 KeyStore keyStore = KeyStore.getInstance("BKS");ks.load(mActivity.getResources().openRawResource(R.raw.emm_truststore), STOREPASSWORD.toCharArray());

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");
        kmf.init(ks, KEYPASSWORD.toCharArray());
        TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");
        tmf.init(ks);
        SSLContext sslContext = null;
        sslContext = SSLContext.getInstance("TLS");
        sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
        chatserver.setWebSocketFactory(new DefaultSSLWebSocketServerFactory(sslContext));

        chatserver.start();

This is client code....

 factory.setVerifyHostname(false);
            factory.setServerName("prince.com");
            WebSocket ws = null;
            try {
                ws = factory.createSocket("wss://localhost:55555");
            } catch (IOException e) {
                e.printStackTrace();
            }

            ws.addListener(new WebSocketListener() {
                @Override
                public void onStateChanged(WebSocket websocket, WebSocketState newState) throws Exception {
                    Log.d(TAG, " onStateChanged ");
                }

                @Override
                public void onConnected(WebSocket websocket, Map<String, List<String>> headers) throws Exception {
                    Log.d(TAG, " onConnected ");
                }

                @Override
                public void onConnectError(WebSocket websocket, WebSocketException cause) throws Exception {
                    Log.d(TAG, " onConnectError " + cause);
                }

                @Override
                public void onDisconnected(WebSocket websocket, WebSocketFrame serverCloseFrame, WebSocketFrame clientCloseFrame, boolean closedByServer) throws Exception {
                    Log.d(TAG, " onDisconnected ");
                }


            });
            ws.connect();
            ws.sendText("Hellooooooooooooooooooooooooooooooooo.");
            System.out.println(" Sending Hello to Server ");

Log...

Can anyone please suggest what am doing wrong.

I am using self signed certificate for making web socket secure (WSS). Sample code reference will be appreciated.
