Socket.io event works randomly - node.js

Question

What I'm trying to do is to emit a event based on the progress of my jobs. It's working in the Gateway(proxy) side, the logs appear, etc, but when I'm consuming the event on the front-end, sometimes it works, sometimes not, and it throws 'ping timeout' error in the console. If I restart the nodejs service a few times it works.
I'm open to ideas of alternative ways to implement this feature.
SocketController
export default class SocketController {
socket: any;
interval: any;
instance: any;
queue: any;
constructor(server) {
// Creating Websocket connection
this.instance = new Server(server, {
cors: { origin: process.env.FRONTEND_URL },
path: "/socket.io/"
});
this.socket = null;
this.queue = null;
this.instance.on("connection", (socket) => {
let connectedUsersCount =
Object.keys(this.instance.sockets.sockets).length + 1;
let oneUserLeft = connectedUsersCount - 1;
console.log("New client connected ", connectedUsersCount);
// Assign socket to the class
this.socket = this.socket == null ? socket : this.socket;
/*
if (this.interval) {
clearInterval(this.interval);
}
*/
// initialize Queue
this.queue = this.queue === null ? new QueueService(socket) : this.queue;
socket.on("disconnect", () => {
console.log("Client disconnected ", oneUserLeft);
// clearInterval(this.interval);
});
});
}
QueueService
export default class QueueService {
channels: any;
socket: any;
constructor(socket: any) {
this.channels = ["integrationProgress", "news"];
this.socket = socket;
integrationQueueEvents.on("progress", (job: any) => {
console.log("Job Progressing", job);
this.socket.emit("integrationProgress", { status: true, data: job.data })
});
integrationQueueEvents.on("active", ({ jobId }) => {
console.log(`Job ${jobId} is now active`);
});
integrationQueueEvents.on("completed", ({ jobId, returnvalue }) => {
console.log(`${jobId} has completed and returned ${returnvalue}`);
this.socket.emit("integrationComplete", {
status: true,
message: returnvalue
});
});
integrationQueueEvents.on("failed", ({ jobId, failedReason }) => {
console.log(`${jobId} has failed with reason ${failedReason}`);
this.socket.emit("integrationProgress", {
status: false,
message: failedReason
});
});
}
}
Front-End
const socket = io(process.env.GATEWAY_URL, {
path: "/socket.io/"
});
socket.on("connect_error", (err) => {
console.log(`connect_error due to ${err.message}`);
socket.connect();
});
socket.on("disconnect", (socket) => {
console.log(socket);
console.log("Client disconnected ");
});
socket.on("connect", (socket) => {
console.log("Client Connected ");
console.log(socket);
});
socket.on("integrationProgress", async (socket) => {
try {
console.log(`Progress: ${socket.data}`);
updateJob(socket.data);
} catch (err) {
console.log(err);
}
});
