unable to send mail using laravel php - php

Question

I am unable to send a test mail. I am using laravel php.
my .env file:
MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=ca**********4b
MAIL_PASSWORD=04**********7b
MAIL_ENCRYPTION=tls
my mail.php:
'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'mailtrap.io'),
'port' => env('MAIL_PORT', 2525),
'from' => ['address' =>'******#gmail.com', 'name' => '****'],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => env('ca**********4b'),
'password' => env('04**********7b'),
'sendmail' => '/usr/sbin/sendmail -bs',
my controller:
<?php
namespace App\Http\Controllers;
use Request;
use Response;
use App\Users;
use Mail;
class MailController extends Controller
{
public function basic_email(){
$data = array('name'=>"Virat Gandhi");
Mail::send(['text'=>'welcome'], $data, function($message) {
$message->to('******#gmail.com', '*****')->subject
('Laravel Basic Testing Mail');
$message->from('"******#gmail.com','Virat Gandhi');
});
return "Basic Email Sent. Check your inbox.";
}
}
i am getting this error:
Swift_TransportException in AbstractSmtpTransport.php line 383:
Expected response code 250 but got code "530", with message "530 5.7.1 Authentication required
"
tried clearing cache by php artisan config:cache
what do i need to try more?

I believe it's gonna be firewall issue, have you tried to connect to gmail provider ? it's a good way to catch the error
