Django-芹菜连接被拒绝

Question

My site is having 502 errors when the user requests something that requires the server to send an e-mail. I narrowed it down to an issue with celery, but I'm having problems resolving it. I tried to get celery's status, and I received a connection refused error (traceback below). I restarted all the processes using supervisor as well. Any help would be much appreciated. Thank you.

Traceback (most recent call last):

Answer 1

What is your broker back-end ? (The value of BROKER_URL in celery config file )

Is rabbitmq-server running? if not run it:

service rabbitmq start

And then restart your celery script.
