Websocket error ECONNRESET

[sb302]

@admin , I am using the Node.js SDK for connecting to Websocket (v 2.0), but everytime I am trying to connect, it is giving an error 'ECONNRESET'. My code is the following: -

let web_socket = new WebSocketClient({
            clientcode: config.get("client_id"),
            jwttoken: jwtToken,
            apikey: config.get("api_key"),
            feedtype: "order_feed"
        });

        web_socket.connect().then(() => {
            // ACTION_TYPE: subscribe | unsubscribe FEED_TYPE: order_feed
            web_socket.fetchData("subscribe", "order_feed");

            setTimeout(function () {
                web_socket.close();
            }, 60000)
        })
        .catch((e) => {
            console.error(e);
        });

        web_socket.on('tick', onTick);
