Unable to get queues: 'invalid username-password pair or user is disabled.'

[wlane]

Describe the bug
I am currently running Airflow in docker, which employs the CeleryExecutor. Celery utilizes a Redis Sentinel cluster with ACL enabled as the message broker. When starting flower, it seems ok, but when I press the Broker tab, the following error message occurs:

$ sudo docker logs --tail 100 -f airflow-flower-1

BACKEND=sentinel
DB_HOST=xxxxxxx
DB_PORT=26379
