PHP Mailer is giving me error 404 - php

Question

Here is my html for my form, action and everything else should be correct, I'm thinking its probably my php?
<form class="form-inline" role="form" method="post" action="index.php">
<div class="form-group">
<label for="inputName">Name</label>
<input type="text" class="form-control" id="inputName" placeholder="Jane Doe">
</div>
<div class="form-group">
<label for="inputEmail">Email</label>
<input type="email" class="form-control" id="inputEmail" placeholder="jane.doe#example.com">
<button type="submit" class="btn btn-default" id="formBtn">Send Email</button>
</div>
</form>
Here is my PHP that I copied and then changed the details to fit myself from github.
<?php
require 'phpMailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->SMTPDebug = 3;
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'email#gmail.com'; // SMTP username
$mail->Password = 'password'; // SMTP password
$mail->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465; // TCP port to connect to
$mail->From = 'email#gmail.com';
$mail->FromName = 'Bradley';
$mail->addAddress('email#gmail.com', 'Brad'); // Add a recipient
$mail->addReplyTo('email#gmail.com', 'Reply address');
$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Email from Vote Unanimous';
$mail->Body = 'You have a new email from your Vote Unanimous account. You should have a name and new email';
$mail->AltBody = 'You have a new email from your Vote Unanimous account. You should have a name and new email';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}

Thanks for helping out. I had to change my password in my gmail account to make it work
