Laravel Echo with NodeJS HTTPS doesn't work

Question

I've been developing this NodeJS application that takes advantage of Laravel Echo's functionalities to receive information from a server through socket connection.

Server-side Laravel Echo Server with Laravel 5.7.19

Client-side "laravel-echo": "^1.5.2" "socket.io": "^2.2.0"

import Echo from '../../node_modules/laravel-echo/dist/echo.common.js'
import Socketio from 'socket.io-client';

let echo = new Echo({ 

  broadcaster: 'socket.io',
  host: 'https://smartfish.danymota.com:8080/',
  encrypted: true,
  secure: true,
  client: Socketio,
  auth: {
    headers: {
      'Authorization': 'Bearer ' + this.token.bearerToken,
    },
  },
});
echo.private('central.' + macAddress)
  .listen('RulesUpdated', (response) => {
    handleRules(JSON.parse(response.aquarios))
    console.log(new Date().toLocaleString() + " - Rules updated")
  })

Problem Everything works fine in Http, when I switch to HTTPS it just stops working. Also, the socket connection doesn't reach the server (or at least Laravel-echo-server doesn't log it)

IMPORTANT - What I've tried

1. Ran the application through Browserify, and then on the browser (it works just fine on a browser, even with HTTPS)

2. Played around with different ports (Again, it works with HTTP, so ports are likely not the problem)

3. Changed the URL to wss://, /socket.io

4. Forced socket.io to include a secure: true on options

5. Changed the version of Laravel Echo

6. Tried importing both echo.common.js and echo.js

Notes

/api/broadcasting/auth - This is working, so problem is likely not here

Laravel echo server configuration

    {
    "authHost": "https://smartfish.danymota.com",
    "authEndpoint": "/api/broadcasting/auth",
    "clients": [{
        "appId": "f7506b5e7118092c",

    }],
    "database": "redis",
    "databaseConfig": {
        "redis": {},
        "sqlite": {
            "databasePath1": "/database/laravel-echo-server.sqlite"
        }
    },

        "allowHeaders": "Origin, Content-Type, X-Auth-Token, X-Requested-With, Accept, Authorization, X-CSRF-TOKEN, X-Socket-Id"
    }
}

Thank you all in advance.

I've solved this problem by adding a flag rejectUnauthorized: false to laravel echo.

  this.echo = new Echo({
  broadcaster: 'socket.io',
  host: config.ECHO_SERVER,
  client: Socketio,
  rejectUnauthorized: false,
  auth: {
    headers: {
      'Authorization': 'Bearer ' + this.token.bearerToken,
    },
  },
})
