flower UI doesn't show workers

I have set up airflow to execute workflows with celeryExecuter. I have started the webserver, scheduler and worker and they run just fine. But flower UI doesn't show any workers.

The output of airflow worker is:

/usr/local/lib/python2.7/dist-packages/psycopg2/__init__.py:144: UserWarning: The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead. For details see: <http://initd.org/psycopg/docs/install.html#binary-install-from-pypi>.
  """)

And the output of airflow flower is:

But flower doesn't show any information about workers or tasks and generates following error on CLI:

[E 180802 11:29:55 broker:82] RabbitMQ management API call failed: [Errno 111] Connection refused

Any ideas as to what's wrong?

Well, I was able to solve the problem. It turns out I was supposed to add export C_FORCE_ROOT=true to my ~/.bashrc file before running the worker. This happens when you're executing the worker as root.
