Sending mail with Symfony (SwiftMail & Gmail) - gmail

Question

I'm trying to use Swiftmailer with Symfony 2.4.
Here is my config.yml :
# This file is auto-generated during the composer install
# parameters:
# mailer_transport: gmail
# mailer_host: smtp.gmail.com
# mailer_user: jules.truong.pro#gmail.com
# mailer_password: XXXXXX
# mailer_port: 465
# locale: fr
# secret: XXXX
And this is parameters.yml
# Swiftmailer Configuration
# swiftmailer:
# transport: %mailer_transport%
# username: %mailer_user%
# password: %mailer_password%
My code is pretty basic :
# $request = $this->get('request');
# $dataSubject = $request->query->get('lbSubject');
# $dataEmail = $request->query->get('lbEmail');
# $dataMessage = $request->query->get('lbMessage');
# //Récupération du service
# $mailer = $this->get('mailer');
#
# // Création de l'e-mail : le service mailer utilise SwiftMailer, donc nous créons une instance de Swift_Message
# $message = \Swift_Message::newInstance()
# ->setSubject($dataSubject)
# ->setFrom($dataEmail)
# ->setTo('julestruonglolilol#email.com')
# ->setBody($dataMessage);
#
# try
# {
# if (!$mailer->send($message, $failures))
# {
# return new Response('Erreur' . $failures,400);
# }
# return new Response('OK',200);
# }
# catch(Exception $e)
# {
# return new Response('Erreur' . $failures,400);
# }
At the end, it returns an error
Connection could not be established with host smtp.gmail.com
This is pretty offensive because i know my password .
After a few minutes, i receive and email that tells me that someone tried to hack my account etc ...
Oh and i'm running this with Wamp, so in local.
Is this my code that has a problem or Google maybe ?
Thanks

Try adding the following to your swiftmail configuration as GMail requires encryption/ssl connection
encryption: ssl
