celery flower gives unknown worker

Question

I'm using celery with redis backend.

i am passing CELERY_RESULT_BACKEND with the correct redis url and also the broker url to the Celery app config.

I start flower by giving the path to my Celery app with -A and also set the --inspect_timeout=30 argument to allow for slow response from worker. I get Unknown worker 'celery@' when clicking on the worker in the UI.

Any ideas how to get this working?

There is a Refresh button on the dashboard page. It refreshes workers by resending inspect command. If you launch workers after flower just refresh workers.

The Refresh button is a choice under the drop down menu that has Shut Down selected by default. In order to Refresh, you have to select a worker (or all of them) first.According here: https://github.com/mher/flower/issues/395
