Answer 1

I just had this same problem.

It looks like the server is not able to ping the destination address.

I did a quick restart of my dev server and everything is back to normal.

Hope that helps.

Edit and following this file: config / mail.php

'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'your mail host'),
'port' => env('MAIL_PORT', '465'),
'from' => [
        'address' => env('MAIL_FROM_ADDRESS', 'Your email address'),
        'name' => env('MAIL_FROM_NAME', 'Your email Name'),
'encryption' => env('MAIL_ENCRYPTION', 'ssl'),

Don't touch for these two lines

'username' => env('MAIL_USERNAME'),

'password' => env('MAIL_PASSWORD'),

Edit and following this file: /.env

MAIL_DRIVER=smtp
MAIL_HOST=your mail host
MAIL_PORT=465
MAIL_USERNAME=Your smtp email address
MAIL_PASSWORD=Your smtp password
MAIL_ENCRYPTION=ssl

MAIL_FROM_ADDRESS=Your email address
MAIL_FROM_NAME="Your email Name"

Edit .env file :

MAIL_HOST=smtp.gmail.com

Edit Config/mail.php file :

'host' => env('MAIL_HOST', 'smtp.mailgun.org'),

.env and mail.php should both correspond to each other .

Answer 4

Use below code in .env file:

MAIL_ENCRYPTION= TLS

Try to clear cache , config cache , and restart apache2.

It works.

Answer 5

After modify your settings you need to run: php artisan config:cache

Without those laravel will use old ones.

Answer 6

The problem is actually a simple typo. In your .env file, change this:

MAIL_DRIVER=smtp MAIL_HOST=mailtrap.io

to this:

MAIL_DRIVER=smtp MAIL_HOST=smtp.mailtrap.io

I prepended the smtp. to the host
