I had this problem too. I see these logs/failure whenever I move to a new
aws instance. I solve it by running the steps mentioned in this post
https://groups.google.com/d/msg/openedx-ops/1SsdJ39IQRc/xx5Vsw9vJnIJ
To repeat the steps:
1)sudo rabbitmqctl add_user celery celery
2)sudo rabbitmqctl set_permissions celery ".*" ".*" ".*"
3)sudo service rabbitmq-server restart
Please go through the original link to get description of what the problem
is about and what the steps are about. Also there is information about
security tips on a production environment.
Happy Diwali!
