Laravel - Connection could not be established with host smtp.gmail.com [ #0]

Question

I'm trying to send an email from Gmail using Laravel from localhost. I'm getting this error: Connection could not be established with host smtp.gmail.com [ #0]

I'm using ssl with port 465. I also tried 587 but it didn't work.

I also tried this but it didn't work. I found a lot of people suffering from the same problems, but the solutions I found didn't work.

I think it helps full: [The connection could not be established with host smtp.gmail.com?](https://devnote.in/the-connection-could-not-be-established-with-host-smtp-gmail-com) — Fefar Ravi, Oct 12 '21 at 16:24

Editor's note: disabling SSL verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint (such as GitHub or some other remote Git host), and you'll be vulnerable to a Man-in-the-Middle Attack.

Be sure you fully understand the security issues before using this as a solution.

In Laravel project directory, edit config/mail.php and add the following:

'stream' => [
        'ssl' => [
            'allow_self_signed' => true,
            'verify_peer' => false,
            'verify_peer_name' => false,
        ],
    ]

It worked for me.

Fyi, my SMTP settings are:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
MAIL_USERNAME=[Full Gmail Address]
MAIL_PASSWORD=[Google App Password obtained after two step verification on Google Account Page]
MAIL_ENCRYPTION=ssl

I didn't need the stream part. What made the difference was the app password after the two step verification, and php artisan config:cache – jaumebalust Oct 06 '20 at 15:30
this solved my problem – Mohsin Khan Nov 06 '21 at 13:36

verify peer option location has been changed, just define `'verify_peer' => false` into `'smtp'` array for Laravel 9.x – spetsnaz Jan 19 '23 at 14:26

This one line change in .env file will make it work

MAIL_DRIVER=sendmail

If it also has no effect try to switch between the mail port

MAIL_PORT=587

Or

MAIL_PORT=465

This will work only if you enable "Allow Less secure app access" under google account

In your .env file you will need to set the email address and password of your email account:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=test@gmail.com
MAIL_PASSWORD=testpassword

and in mail.php

<?php

return [
    'driver' => env('MAIL_DRIVER', 'smtp'),
    'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
    'port' => env('MAIL_PORT', 587),
    'from' => ['address' => 'yourEmail@gmail.com', 'name' => 'Your Title'],
    'encryption' => 'tls',
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'),
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,
];

and clear the config cache with:

php artisan config:cache

for live server also need username and password? – Chintan Mathukiya Jul 29 '17 at 07:55 — Chintan Mathukiya, Jul 29 '17 at 07:55

here's what is working with me

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<your email>
MAIL_PASSWORD=<your app password>
MAIL_ENCRYPTION=tls

if you are two auth verification with your account , should be generate new app password and use into you env file. this is what working with me.

Have you tried changing the encryption to tls? I currently use a Gmail SMTP sever to send emails from my Laravel app. I use TLS and port 587

Thats work for me! when I use apache in windows, I need to put tls. So maybe it's an ssl configuration problem. – rebduvid Sep 17 '17 at 20:36

in localhost you can set your MAIL_DRIVER=smtp but on real server like cpanel you must to set MAIL_DRIVER=sendmail and edit your config/mail.php 'default' => env('MAIL_MAILER', 'sendmail'), but its not good idea because after you send mail on google you get error on gmail like this :

Be careful with this message Gmail could not verify that it actually came from tenetup.reminderme@gmail.com. Avoid clicking links, downloading attachments, or replying with personal information.
