Laravel: Connection could not be established with host "live.smtp.mailtrap.io:587": stream_socket_client(): Unable to connect to

Question

I'm currently using Laravel as my framework for a website.

Error Code:

Connection could not be established with host "live.smtp.mailtrap.io:587": stream_socket_client(): Unable to connect to live.smtp.mailtrap.io:587 (Connection refused)

I am trying to use 'MailTrap' to send an order form to client's email. I followed most of the instructions from online and made it work locally using php artisan serve.

But the problem is, when I deploy it to a web hosting server (GoDaddy Economy Linux Hosting with cPanel), the error code appears.

Here are the code snippets:

env:

MAIL_MAILER=smtp
MAIL_HOST=live.smtp.mailtrap.io
MAIL_PORT=587
MAIL_USERNAME=xxx
MAIL_PASSWORD=xxx
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS="no-reply@website-name.com"
MAIL_FROM_NAME="${APP_NAME}"

config/mail.php:

<?php

return [

Post Route:

    /**

    public function EmailContact(Request $request)
        {
            $contactName = $request->input('name');
            $contactEmail = $request->input('email');
            $contactNumber = $request->input('contact');
            $contactContent = $request->input('message');
            Mail::to('marketing@jpmarx.com')->send(new SendContact($contactName, $contactEmail, $contactNumber, $contactContent));
            return Redirect::route('ContactSuccess');
        }

    public function EmailOrder(Request $request)
        {
            $fullName = $request->input('orderName');
            $cusEmail = $request->input('orderEmail');
            $cusAddress = $request->input('orderAddress');
            $cusContact = $request->input('orderContact');
            $fbLink = $request->input('fblink');
            $craylingQuan = $request->input('craylingsQuantity');
            $juvenileQuan = $request->input('juvenilesQuantity');
            $breederType = $request->input('breederRadio');
            $breederQuan = $request->input('breeders');
            Mail::to('marketing@jpmarx.com')->send(new SendOrder($fullName, $cusEmail, $cusAddress,
            $cusContact, $fbLink, $craylingQuan, $juvenileQuan, $breederType, $breederQuan));
            return Redirect::route('ContactSuccess');
        }

I tried using all the available ports provided by Mailtrap such as 587, 2525, and 25. I also added a code snippet I got from a previous question in config file, but it didn't work.

'stream' => [
        'ssl' => [
            'allow_self_signed' => true,
            'verify_peer' => false,
            'verify_peer_name' => false,
        ],
    ],
