This is the behavior when the broker is network unreachable or not in external_links definition. It works when flower can reach rabbitmq.

Hi,
this statement seems correct to me

when the broker is network unreachable

Change in your docker-compose.yml file the line command to use in the broker url 'rabbitmq' instead of 'localhost'.
(docker image is not aware of localhost and docker-compose is building a network with the declared services as hosts ([https://docs.docker.com/compose/networking/]))
from

command: ["flower", "--address=0.0.0.0", "--broker=amqp://guest:guest@localhost:5672/","--port=5555", "--logging=DEBUG"]

to

command: ["flower", "--address=0.0.0.0", "--broker=amqp://guest:guest@rabbitmq:5672/","--port=5555", "--logging=DEBUG"]
