unable to connect on websockets

I have reactivated my app today early in the morning,but I have since not been able to connect to websockets.

I am using the following code;

const fs = require("fs");
var access_token = fs.readFileSync("./all_keys/access_token.txt").toString();
var api_key_txt = fs.readFileSync("./all_keys/api_key_only.txt").toString();


var KiteTicker = require("kiteconnect").KiteTicker;
var ticker = new KiteTicker({
	api_key: api_key_txt,
	access_token: access_token
});

// set autoreconnect with 10 maximum reconnections and 5 second interval
ticker.autoReconnect(true, 10, 5)
ticker.connect();
ticker.on("ticks", onTicks);
ticker.on("connect", subscribe);

ticker.on("noreconnect", function() {
	console.log("noreconnect");
});

ticker.on("reconnecting", function(reconnect_interval, reconnections) {
	console.log("Reconnecting: attempt - ", reconnections, " innterval - ", reconnect_interval);
});

function onTicks(ticks) {
	console.log("Ticks", ticks);
}

function subscribe() {
	var items = [14451970];
	ticker.subscribe(items);
	ticker.setMode(ticker.modeFull, items);
}
