Sockets with Meteor, Connection Timeout in Flutter

1

Hi Everyone,

Integrated socket io with Meteor using the following code

import io from 'socket.io';
import { Meteor } from 'meteor/meteor';
import { WebApp } from 'meteor/webapp';

const { httpServer } = WebApp;
  
Meteor.startup(()=>{
        io(httpServer).on('connection', (socket)=>{
            console.log("inside socket conection");
            socket.on('hello',(data)=>{
                    console.log('HELLO BISH')
                    console.log(JSON.stringify(data));
                    // console.log(data.text)
                    socket.emit("hello_back", data);
                });
        });
    })

Sockets are working fine on the Web but while connecting these from Flutter App, Getting a connection timeout error. Can anyone suggest to me what can be the issue here?

Deployed the Application both on Heroku & production. Also, checked on HTTP & HTTPS the error is the same for both.

Please help.
