problem sending mail from localhost with phpmailer

I have installed PHP v5.6.25 (I use the 64x version) and wampserver v3.0.6, Apache 2.4.23. I've made some port modifications since I've followed several tutorials on YouTube but I do not remember which lines I've modified on a regular basis.

File php.ini www.dropbox.com/s/vnoxv38qqa67oez/php.ini?dl=0

I am trying to make a mailing system using phpmailer, using as host "smtp.gmail.com" I have enabled access to less secure applications from my gmail account (myaccount.google.com/lesssecureapps).

My PHP file is as follows:

<?php
// This example shows settings to use when sending via Google's Gmail servers.
//

//SMTP needs accurate times, and the PHP time zone MUST be set
//This should be done in your php.ini, but this is how to do it if you don't have access to that
date_default_timezone_set('Etc/UTC');

require 'PHPMailer/PHPMailerAutoload.php';

//Create a new PHPMailer instance
$mail = new PHPMailer;

//Tell PHPMailer to use SMTP
$mail->isSMTP();

//Enable SMTP debugging
// 0 = off (for production use)
// 1 = client messages
// 2 = client and server messages
$mail->SMTPDebug = 2;

//Ask for HTML-friendly debug output
$mail->Debugoutput = 'html';

//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';
// use
// $mail->Host = gethostbyname('smtp.gmail.com');
// if your network does not support SMTP over IPv6

//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
$mail->Port = 587;

//Set the encryption system to use - ssl (deprecated) or tls
$mail->SMTPSecure = 'tls';

//Whether to use SMTP authentication
$mail->SMTPAuth = true;

//Username to use for SMTP authentication - use full email address for gmail
$mail->Username = "*******@gmail.com";

//Password to use for SMTP authentication
$mail->Password = "+++++++++";

//Set who the message is to be sent from
$mail->setFrom('[email protected]', 'No responder');

//Set an alternative reply-to address
//$mail->addReplyTo('[email protected]', 'First Last');

//Set who the message is to be sent to
$mail->addAddress('*********@gmail.com', 'Nombre Destinatario');

//Set the subject line
$mail->Subject = 'PHPMailer GMail SMTP test';

$nombre='Federico Lorca';
//Read an HTML message body from an external file, convert referenced images to embedded,
//convert HTML into a basic plain-text alternative body
$mail->Body = "<h1>Prueba de correo</h1><br><br>Mensaje de prueba enviado por {$nombre} con phpmailer en formato html<br>";

//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';

//Attach an image file
//$mail->addAttachment('images/phpmailer_mini.png');

//send the message, check for errors
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
    } else {
    echo "Message sent!";
}  ?>

Displays the following error:
