Troubleshooting empty Laravel Redis queue (cause: APP_NAME change)

Be aware that if you’re using Redis to handle a queue, don’t rename your APP_NAME environment variable while there are jobs on the queue, as they will all mysteriously disappear.

This is because the APP_NAME is used as a prefix to the Redis key, so Laravel will fail to find any jobs that have already been added.

'redis' => [

'client' => env('REDIS_CLIENT', 'predis'),

'options' => [
'cluster' => env('REDIS_CLUSTER', 'predis'),
'prefix' => Str::slug(env('APP_NAME', 'laravel'), '_').'_database_',
