The problem is that you are trying to connect to a local instance of RabbitMQ. Look at this line in your settings.py
BROKER_URL = 'amqp://guest:guest@localhost:5672/'
If you are working currently on development, you could avoid setting up Rabbit and all the mess around it, and just use a development version of a message queue with the Django database.
Do this by replacing your previous configuration with:
BROKER_URL = 'django://'
…and add this app:
INSTALLED_APPS += ('kombu.transport.django', )
Finally, launch the worker with:
./manage.py celery worker --loglevel=info

I got this error because rabbitmq was not started. If you installed rabbitmq via brew you can start it using brew services start rabbitmq

If you are workling on a production environment,
You have to first install and setup a rabbitmq server. You can refer rabbitmq website for installation steps.
In settings you have to write this lines:
CELERY_RESULT_BACKEND='djcelery.backends.database:DatabaseBackend',
BROKER_URL = 'amqp://guest:guest@localhost:5672//'
After all setup of rabitmq server you have to run this two command,
export C_FORCE_ROOT='true'
celery -A transcoder(name of app) worker --loglevel=info

While you are installing Celery via pip you should select the version that you want to work with such as redis, rabbitmq, django etc.
As referred in docs: https://pypi.org/project/celery/
Bundles
Celery also defines a group of bundles that can be used to install Celery and the dependencies for a given feature.You can specify these in your requirements or on the pip command-line by using brackets. Multiple bundles can be specified by separating them by commas.
Example:
$ pip install "celery[librabbitmq]"
$ pip install "celery[librabbitmq,redis,auth,msgpack]"

If all above solutions are not working, you can try with this:
turn off your network connection (wifi or wire).
It’s so weird but sometime it’s work for me!
Seem it relates to the local network device instead of RabbitMQ service.
