Laravel-backup: Expected response code 220 but got an empty response

[n0n0n0n0]

Laravel version: 6.5.2
Backup: 6.7.4
PHP: 7.3.2

Cron: $schedule->command('backup:run --only-db')->hourly();

Hello, i've got today that error, tried to reproduce by running backup again, but no success. I thought i turned off mail notifications by these configuration:

 'notifications' => [

        'notifications' => [
            \Spatie\Backup\Notifications\Notifications\BackupHasFailed::class         => [],
            \Spatie\Backup\Notifications\Notifications\UnhealthyBackupWasFound::class => [],
            \Spatie\Backup\Notifications\Notifications\CleanupHasFailed::class        => [],
            \Spatie\Backup\Notifications\Notifications\BackupWasSuccessful::class     => [],
            \Spatie\Backup\Notifications\Notifications\HealthyBackupWasFound::class   => [],
            \Spatie\Backup\Notifications\Notifications\CleanupWasSuccessful::class    => [],
        ],

        /*
         * Here you can specify the notifiable to which the notifications should be sent. The default
         * notifiable will use the variables specified in this config file.
         */
        'notifiable' => \Spatie\Backup\Notifications\Notifiable::class,

        'mail' => [
            'to' => '',
        ],

        'slack' => [
            'webhook_url' => '',

            /*
             * If this is set to null the default channel of the webhook will be used.
             */
            'channel' => null,
        ],
    ],

but according to log it tried to send mail somewhere. I didn't get that error before and after running again there was no error. But definitly something went wrong.

The error is from your mail service, not the package. Check your mail details if correct and try to change email provider to see if it works

[n0n0n0n0]

@djunehor i know that this error from mail service. Did you read what i wrote or just checked callstack? I'm UNABLE TO TURN OFF mail notifications, even with this config:

'notifications' => [

        'notifications' => [
            /*
            \Spatie\Backup\Notifications\Notifications\BackupHasFailed::class         => [],
            \Spatie\Backup\Notifications\Notifications\UnhealthyBackupWasFound::class => [],
            \Spatie\Backup\Notifications\Notifications\CleanupHasFailed::class        => [],
            \Spatie\Backup\Notifications\Notifications\BackupWasSuccessful::class     => [],
            \Spatie\Backup\Notifications\Notifications\HealthyBackupWasFound::class   => [],
            \Spatie\Backup\Notifications\Notifications\CleanupWasSuccessful::class    => [],
            */
        ],

        /*
         * Here you can specify the notifiable to which the notifications should be sent. The default
         * notifiable will use the variables specified in this config file.
         */
        'notifiable' => null,

        'mail' => [
            'to' => null,
        ],

        'slack' => [
            'webhook_url' => '',

            /*
             * If this is set to null the default channel of the webhook will be used.
             */
            'channel' => null,
        ],
    ],

it still trying to sent it to [email protected]

[djunehor]

I can't replicate that behaviour on my installation, which means the settings work for me. Can you try clearing config cache php artisan config:clear, then run php artisan backup:run again.

[abdulRahman-coder770]

this error makes me very tired. I try and try all solution but no change ):
