Created on 24 Jan 2018 · 5Comments · Source: laravel/horizon

After run command:
php artisan horizon
Return the message: Horizon started successfully
And after 2 seconds return:
In QueueManager.php line 172: No connector for [redis]
This error returned periodically in the console. In Horizon dashboard status is active

ENV:
QUEUE_DRIVER=redis
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

database.php

'redis' => [
'client' => 'predis',
'default' => [
'host' => env('REDIS_HOST', '127.0.0.1'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
],
]

queue.php
'redis' => [
'driver' => 'redis',
'connection' => 'default',
'queue' => 'default',
'retry_after' => 90,
]

horizon.php
'GetMedia' => [
'connection' => 'redis',
'queue' => ['getmedia'],
'balance' => 'simple',
'processes' => 2,
'tries' => 2,
]

Where is the probleme? No connector for [redis]?

And is it not clear to me if Horizon monitor and processing jobs or just monitor it?

I'm sure the originator of this issue has now solved this issue but I had the same recently and wanted to quickly share the cause in case it helps someone else.
Another package we had installed (AWS Worker thingy by Dusterio) was resolving an instance of the QueueManager singleton in its own service provider. This was blowing away all the connectors that had been loaded into the QueueManager originally which causes the 'No connector for [redis] error'. The issue was clear when I could see connectors loaded and then the array suddenly becoming empty. in debugging.
A project-wide search for QueueManager revealed the problem vendor package.
Hope this helps someone.

if you change the horizon config to queue default do you still have the same problem?

.env
APP_ENV=qa

horizon.php

'qa' => [
                'connection' => 'redis',
                'queue' => ['default'],
                'balance' => 'simple',
                'processes' => 3,
                'tries' => 3,
]
