production.ERROR: Connection refused [tcp://127.0.0.1:6379] {"exception":"[object] (Predis\Connection\ConnectionException(code: 111): Connection refused [tcp://127.0.0.1:6379] at /home/websiteroot/website/vendor/predis/predis/src/Connection/AbstractConnection.php:155)

server is centos 7 using WHM panel redis is installed predis is also installed with on whm extention installer

before the update everything was working fine

in the .env file

QUEUE_CONNECTION=redis

REDIS_CLIENT=predis
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

in horizon config

'production' => [
            'supervisor-1' => [
                'connection' => 'redis',
                'queue' => ['default'],
                'balance' => 'simple',
                'processes' => 10,
                'tries' => 3,
                'timeout' => 1200,
            ],
        ],

in the queue config

'redis' => [
            'driver' => 'redis',
            'connection' => 'default',
            'queue' => env('REDIS_QUEUE', 'default'),
            'retry_after' => 900,
            'block_for' => null,
        ],

the job that is run in console/kernel

$schedule->call(function () {
            \App\Jobs\OrderChecked::dispatch();
        })->everyMinute();

and this is the stack
