Help with Contact Form

Hi, im having issues with the contact form, when submitting I get the following error:

"jquery.js:2 POST file:///home/jid/EnerlinkWeb/include/form.php net::ERR_FAILED"

You can check a live version of the web in enerlink

Also, this is my form.php, i followed the documentation for editing it:

<?php

use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer();

/* Add your SMTP Codes after this Line */
$mail->isSMTP();
$mail->SMTPDebug = 0;
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "contacto@enerlink.cl";
$mail->Password = "[Redacted]";
// End of SMTP

The html is from the templates but i have removed the Captcha.
