Tick data listener not working

Hi there,

I was getting the Tick data for Nifty 50 but suddenly the listener is not working.
Not sure where the issue is, do we get the tick data only during market hours?

Here is the code!!

public Double getMarketCurrentPriceforNifty(KiteConnect kiteConnect) throws WebSocketException, IOException, KiteException {
        final KiteTicker tickerProvider = new KiteTicker(kiteConnect.getAccessToken(), kiteConnect.getApiKey());
        ArrayList<Long> tokens = new ArrayList<>();
        try {
            tokens.add(Long.parseLong("256265"));
            tickerUsage(kiteConnect, tokens, tickerProvider);
        } finally {
            // Unsubscribe for a token.
            tickerProvider.unsubscribe(tokens);
            // After using com.zerodhatech.com.zerodhatech.ticker, close websocket connection.
            tickerProvider.disconnect();
        }
        //setting this to test the logic
        //setNiftyPrice(9199.05);
        return niftyPrice;
    }


 public void tickerUsage(KiteConnect kiteConnect, ArrayList<Long> tokens, KiteTicker tickerProvider) throws IOException, WebSocketException, KiteException {

        tickerProvider.setOnConnectedListener(new OnConnect() {
            @Override
            public void onConnected() {
                /** Subscribe ticks for token.
                 * By default, all tokens are subscribed for modeQuote.
                 * */
                tickerProvider.subscribe(tokens);
                tickerProvider.setMode(tokens, KiteTicker.modeLTP);
            }
        });

        tickerProvider.setOnDisconnectedListener(new OnDisconnect() {
            @Override
            public void onDisconnected() {
                // your code goes here
            }
        });

        /** Set listener to get order updates.*/
        tickerProvider.setOnOrderUpdateListener(new OnOrderUpdate() {
            @Override
            public void onOrderUpdate(Order order) {
                System.out.println("order update "+order.orderId);
            }
        });

        /** Set error listener to listen to errors.*/
        tickerProvider.setOnErrorListener(new OnError() {
            @Override
            public void onError(Exception exception) {
                //handle here.
            }

            @Override
            public void onError(KiteException kiteException) {
                //handle here.
            }

            @Override
            public void onError(String error) {
                System.out.println(error);
            }
        });

        tickerProvider.setOnTickerArrivalListener(new OnTicks() {
            @Override
            public void onTicks(ArrayList<Tick> ticks) {
                NumberFormat formatter = new DecimalFormat();
                System.out.println("ticks size "+ticks.size());
                if(ticks.size() > 0) {
                    niftyPrice = Double.isNaN(ticks.get(0).getLastTradedPrice())?0.0:ticks.get(0).getLastTradedPrice();
                    System.out.println("LTP:"+niftyPrice);
                    System.out.println("open::"+ticks.get(0).getOpenPrice());
                    System.out.println("close::"+ticks.get(0).getClosePrice());
                    System.out.println("high::"+ticks.get(0).getHighPrice());
                    System.out.println("low::"+ticks.get(0).getLowPrice());
                }
            }
        });
        // Make sure this is called before calling connect.
        tickerProvider.setTryReconnection(true);
        //maximum retries and should be greater than 0
        tickerProvider.setMaximumRetries(10);
        //set maximum retry interval in seconds
        tickerProvider.setMaximumRetryInterval(30);

        /** connects to com.zerodhatech.com.zerodhatech.ticker server for getting live quotes*/
        tickerProvider.connect();

        /** You can check, if websocket connection is open or not using the following method.*/
        boolean isConnected = tickerProvider.isConnectionOpen();
        System.out.println(isConnected);

       
        tickerProvider.setMode(tokens, KiteTicker.modeLTP);
