Java HTTPS: / / websocket cannot connect to Android

I have connected the socket http: / / (with port) the URL is complete and works normally, but I have connected HTTPS: / / (without port) which does not work in Java websocket

I use gradle to rely on 'org. Java websocket: Java websocket: 1.3.0'

WebSocketClient   mWebSocketClient = new WebSocketClient(uri) {
    @Override
    public void onOpen(ServerHandshake serverHandshake) {
        Log.e(TAG, "Websocket: " + "Opened");
        mWebSocketClient.send("Hello from " + Build.MANUFACTURER + " " + Build.MODEL);
    }

    @Override
    public void connect() {
        super.connect();
        //Log.e(TAG, "Websocket: " + "connect");
        SharedPreference.storeValue(mContext, SharedPreference.WEB_SOCKET_STATUS, SharedPreference.WEB_SOCKET_CONNECT);
    }
}

resolvent:

I found a solution!) If you want to use WSS: / /, set setwebsocketfactory

public void connect() {

    final String url = "wss://echo.websocket.org";
    URI uri=null;
    try{
        uri = new URI(url);
    }
    catch (URISyntaxException e) 
    {
        Log.e(TAG, e.getMessage());
        return;
    }
    mWebSocketClient = new WebSocketClient(uri) {
        @Override
        public void onOpen(ServerHandshake handshakedata) {
            Log.e(TAG,"Connected!");
        }

        @Override
        public void onMessage(String message) {
            Log.e(TAG,"Message: "+message);

        }

        @Override
        public void onClose(int code, String reason, boolean remote) {
            Log.e(TAG,"Disconnected!");

        }

        @Override
        public void one rror(Exception ex) {
            Log.e(TAG,"Error: "+ex.getMessage());

        }
    };

    if (url.indexOf("wss") == 0) {
        try {
            SSLContext sslContext = SSLContext.getDefault();
            mWebSocketClient.setWebSocketFactory(new DefaultSSLWebSocketClientFactory(sslContext));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    mWebSocketClient.connect();
}
