Laravel 8: Connection could not be established with host smtp.gmail.com

Question

I'm trying to send a simple email from my laravel 8 app using Google SMTP server, but it doesn't work, I'm getting this error:

Swift_TransportException
Connection could not be established with host smtp.gmail.com :stream_socket_client(): SSL:

or

stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

I found many SO post regarding this issue but none of them worked for me, here's a list of what I have tried:

Enabling less secure apps in the google account
using ports 465 and 587
Using smtp.googlemail.com and smtp.gmail.com
Using MAIL_ENCRYPTION=tls and ssl
Changing 'stmp' to 'sendmail'
Blocking switmailer's ssl constraint

Is there something else I can try?

Here's my mail configuration, although I've tried many versions of it:

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=address@gmail.com
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=null
MAIL_FROM_NAME="${APP_NAME}"

Try this and add the extra auth mode env variable

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=direction@gmail.com
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=null
MAIL_FROM_NAME="${APP_NAME}"
MAIL_AUTH_MODE=login

Now go to config/mail.php

and change

    'smtp' => [
        'transport' => 'smtp',
        'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
        'port' => env('MAIL_PORT', 587),
        'encryption' => env('MAIL_ENCRYPTION', 'tls'),
        'username' => env('MAIL_USERNAME'),
        'password' => env('MAIL_PASSWORD'),
        'timeout' => null,
        'auth_mode' => null,
    ],

to

    'smtp' => [
        'transport' => 'smtp',
        'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
        'port' => env('MAIL_PORT', 587),
        'encryption' => env('MAIL_ENCRYPTION', 'tls'),
        'username' => env('MAIL_USERNAME'),
        'password' => env('MAIL_PASSWORD'),
        'timeout' => null,
        'auth_mode' => env('MAIL_AUTH_MODE'),
    ],

It keeps failing... throws the second error message shown in the question — Gamopo, Sep 18 '20 at 10:27
Random one. Does your environment have the correct date and time set your the timezone your are in? — Chris Townsend, Sep 19 '20 at 11:40

Finally, it was a problem with Windows. I found some posts pointing that windows just can't execute some mail services. I tried the exact same code in a computer with Ubuntu and it worked at first try.
