Swift_TransportException in StreamBuffer.php line 268: Connection could not be established with host lin01.hkdns.co.za [ #0]

all my details is right. my env

MAIL_DRIVER=smtp
MAIL_HOST=lin01.hkdns.co.za
MAIL_PORT=465
MAIL_USERNAME=[e-mail]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=ssl

In my mail.php

'driver' => env('MAIL_DRIVER', 'smtp'),

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

'port' => env('MAIL_PORT', 587),

'from' => [
    'address' => env('MAIL_FROM_ADDRESS', '[e-mail]'),
    'name' => env('MAIL_FROM_NAME', 'Info'),
],

'encryption' => env('MAIL_ENCRYPTION', 'tls'),

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

'sendmail' => '/usr/sbin/sendmail -bs',

'markdown' => [
    'theme' => 'default',

    'paths' => [
        resource_path('views/vendor/mail'),
    ],
],

Did I miss something or is this a problem on my server?

Answer 1

Sometime it's possible to be "cache" in the laravel.

Use this command and try again:

php artisan config:clear

If not work, try to restart you xampp.

Another option to check if the problem is with your host or your configuration is to use a Gmail server to send a test email.

Puts this in your .env

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=[e-mail]
MAIL_PASSWORD=apppassword
MAIL_ENCRYPTION=tls

Create or use any gmail account and enable the less secure apps more information here

first login to your gmail account and under My account > Sign In And Security > Sign In to google, enable two step verification, then you can generate app password, and you can use that app password in .env file.

Your .env file will then look something like this

MAIL_DRIVER=smtp MAIL_HOST=smtp.gmail.com MAIL_PORT=587 MAIL_USERNAME=[e-mail] MAIL_PASSWORD=apppassword MAIL_ENCRYPTION=tls

Don't forget to run php artisan config:cache after you make changes in your .env file (or restart your server).
