mailer symfony 4 not working - php

Question

I started a project using symfony 4 and the mailer doesn't work, however it should be easy.
before you ask, if i copy past the login and password from my code i'm able to log into my mail account, also i also tried with a netcourrier mail account, also the 2 way authentification is not active and i allowed less secure app to access the mail account.
Here's my conf:
in my .env:
MAILER_URL=gmail://*******#gmail.com:********#localhost
in my controller:
public function contact( \Swift_Mailer $mailer){
$message = (new \Swift_Message('Hello Email'))
->setFrom('*****#gmail.com')
->setTo('*******#gmail.com')
->setBody(
$this->renderView(
// templates/emails/registration.html.twig
'email/registration.html.twig',
array('url' => $url)
),
'text/html'
);
$mailer->send($message);
return $this->render(
'email/index.html.twig');}
and the error i get doing so is :
Connection could not be established with host smtp.gmail.com [ #0]

Answer 1

The problem is your connection SMTP with google, This is correct:
MAILER_URL=smtp://smtp.gmail.com:587?encryption=tls&username=userGmail&password=PassGmail
I have it defined as a service in App/Services, this is the code
<?php
namespace App\Services;
class Enviomail {
private $mailer;
public function __construct(\Swift_Mailer $mailer)
{
$this->mailer = $mailer;
}
public function sendEmail($to, $subject, $texto) {
$message = (new \Swift_Message($subject))
->setFrom('juanitourquiza#gmail.com')
->setTo($to)
->setBody(($texto),'text/html');
return $this->mailer->send($message);
}
}
And to use it I call it from the controller
use App\Services\Enviomail;
........
public function mailsolucion(Request $request, Enviomail $enviomail) {
if ($request->isMethod('POST')) {
$nombre=$request->get("nombre");
$email=$request->get("email");
$numero=$request->get("numero");
$empresa=$request->get("empresa");
$solucion=$request->get("solucion");
if (($nombre=="")||($email=="")||($numero=="")||($empresa=="")){
$this->addFlash(
'alert alert-danger',
'Toda la información es obligatoria'
);
return $this->redirectToRoute('registro');
}
$emailreceptor="juanitourquiza#gmail.com";
$asunto="Soluciones gruporadical.com";
$texto=$this->renderView(
'emails/soluciones.html.twig',
array(
'nombre' => $nombre,
'email' => $email,
'numero' => $numero,
'empresa' => $empresa,
'solucion' => $solucion,
)
);
$enviomail->sendEmail($emailreceptor,$asunto, $texto);
$this->addFlash(
'alert alert-success',
'Pronto nos pondremos en contacto.'
);
return $this->redirectToRoute('registro');
}
return $this->render('AppBundle:App:contacto.html.twig');
}
Works perfect on Symfony 4.x

I think this is not an issue with the mailer, but with gmail. I copied your steps to try to connect through the smtp server of gmail, but got the same error. When using a different MAILER_URL (a different smtp-server) in the .env file, everything works like it should.
