queue:work asks for Redis, but my queue driver is database

Everytime I try to run

php artisan queue:work

I get an error:

[Predis\Connection\ConnectionException]
Connection refused [tcp://127.0.0.1:6379]

But in I use database as a queue driver, not Redis:

.env

QUEUE_DRIVER=database

But php artisan queue:listen works without problems.
