Django Celery socket.error: [Errno 111] Connection refused

Question

When running the command celery status on my production server I get this error:

But, Celery works and the worker do run, what is this error and why can I not run this command?

ubuntu@ip-10-32-9-39:/srv/project/logs/celery$ celery status

Solution 1

Launch from manage.py shell...

sudo python manage.py celery status

This will solve your issue.

Solution 2

In my case, I had to add the following lines at the __init__.py file at the package containing settings.py and celery.py files:

# -*- coding: utf-8 -*-
from __future__ import absolute_import

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app

Check http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html for reference.

@chachan sudo is just for elevated privileges. If you don't need it then you are doing something right!

Its still giving [Errno 111] Connection refused

@cold_coder It's a connection refused message so check you have the correct IP, username or password.
