Regarding Voice App using Twilio Client - Token fetching error while hosting on live domain

[ruchikacrisp]

I am writing this in regard with Voice App using Twilio Client : https://www.twilio.com/code-exchange/voice-app-using-twilio-client

I have implemented everything as per the given instructions on the above written document. Through ngrok tunneling I am able to make calls using my localhost on windows, but when I am trying the same on the live environment in a linux based server I am facing the below error: -
Could not get a token from server!

I had observed the same error while implementing on localhost, but the error was due to the file path and file non-existence. But in the live environment I have done all those changes that helped me previously to sort the issue, but I am unable to get the token on live environment thus am unable to make calls through the live panel..

Below is the configuration of my config.php: -

$TWILIO_ACCOUNT_SID = ' my_account_sid' ;
$TWILIO_AUTH_TOKEN = 'my_account_auth_token';
$TWILIO_TWIML_APP_SID = 'AP57ec82163d9da05de4c7a9f6a7a20987';
$TWILIO_CALLER_ID = '+18553762332';

Below is my directory system in the cpanel: -

1. vendor(autoload.php)
2. voice.php
3. token.php
4. quickstart.js
5. randos.php
6. token.php
7. Other composer, composer.json and index file.

I have given path according to the PHP include as shown below: -

1. voice.php :-
   include("vendor/autoload.php");
   include("config.php");

2. token.php
   include("vendor/autoload.php");
   include("config.php");
   include("randos.php");

Kindly assist with the help using the above given information. Kindly let us know how we can get it running in a live environment.
