NotificationFailed Event never fire

Can you post some of the relevant code? Perhaps the NotificationFailed handler and implementation/usage?

Sure but there's nothing unusial to it. I think the issue is elswhere. I'm quessing there's some issue with error handling wchich causes execution to stop wchich leads to event not being fired.

/// EventServiceProvider.php

protected $listen = [
        'App\Events\Event' => [
            'App\Listeners\EventListener',
        ],
        'App\Events\UserDeleted' => [
            'App\Listeners\UserDeleted',
        ],
        'App\Events\CommentDeleted' => [
            'App\Listeners\CommentDeleted',
        ],
        NotificationFalied::class => [
            NotificationFailedListener::class,
        ],
        NotificationSending::class => [
            NotificationSendingListener::class,
        ],
        'App\Events\NewPostCreated' => [
            'App\Listeners\CreateAdminAction'
        ],
        'App\Events\PostStatusUpdated' => [
            'App\Listeners\NotifyAdministrator'
        ]
    ];

/// NotificationFailedListener.php

<?php

namespace App\Notifications\Listeners;

use Illuminate\Notifications\Events\NotificationFailed;
use Log;

class NotificationFailedListener
{
    public function handle(NotificationFailed $event)
    {
        Log::info('------------------ NOTIFICATION FAILED ');
    }
}

When there's some issue while sending email

// error.log
Failed to authenticate on SMTP server with username "xxxxxxxxxxx" using 3 possible authenticators. Authenticator CRAM-MD5 returned Swift_TransportException: Expected response code 235 but got code "535", with message "535 5.7.0 Invalid login or password
IN ...\vendor\swiftmailer\swiftmailer\lib\classes\Swift\Transport\AbstractSmtpTransport.php:457

and no "NotificationFalied" event fired.

@ardf16

Could it be the below misspelling?

current:

 NotificationFalied::class => [
            NotificationFailedListener::class,
        ],

change to:

 NotificationFailed::class => [
            NotificationFailedListener::class,
        ],
``

That was obvious error on my part but still it's not working. Guess that's what you get working sundays :/.

Now with typos fixed and double-checked i get same thing. No event fired on NotificationFailed. Only Sending and Sent are working.

In console i get error from swift mailer. Nothing from NotificationFailed event.
