Not working after upgrade to Laravel 8.6.0

[venom1979]

After upgrading my application to Laravel 8.6, I'm getting this error when I try to send email using Sendgrid:

  Swift_TransportException

  Connection could not be established with host sendgrid.net :stream_socket_client(): unable to connect to tcp://sendgrid.net:587 (Connection refused)

Are you aware of any compatibility issues with this package and Laravel 8?

Seems the latest version of laravel is v8.0.3 now.
https://github.com/laravel/laravel/releases

Can you tell me an accurate version?

And this library does not use StreamBuffer class.
Is it set sendgrid to MAIL_DRIVER?

According to vendor\laravel\framework\src\Illuminate\Application.php:

    /**
     * The Laravel framework version.
     *
     * @var string
     */
    const VERSION = '8.6.0';

using PHP artisan --version gives the same result. I would have to assume that this is the accurate version?

Here is a link from Laravel News about the release of 8.6: https://laravel-news.com/laravel-8-6-0

MAIL_DRIVER was replaced with MAIL_MAILER as of Laravel 7. I believe I changed it to smtp by mistake. Setting it to 'sendgrid' changes the error:

   InvalidArgumentException

  Unsupported mail transport [].

Here are the relevant .env settings on my app:

MAIL_MAILER=sendgrid
MAIL_HOST=sendgrid.net
MAIL_PORT=587
MAIL_USERNAME='username redacted'
MAIL_PASSWORD='password redacted'
MAIL_ENCRYPTION=tls
SENDGRID_API_KEY='api key redacted'

Thanks for your help!

Oh, sorry I misunderstood the version of laravel-app and laravel-framework.

And that errors may be by miss-configuration in config/mail.php.
Please check to exists following in the file.

    'mailers' => [
        ...
        'sendgrid' => [
            'transport' => 'sendgrid',
        ],

That was it! Had to add transport to the mailer array for sendgrid. Working perfectly now, thanks!
