After some days I found the solution.
From: https://open-edx.readthedocs.io/en/latest/amazon_snapshot_bug.html
First in files /edx/app/edxapp*.auth.json look for:
“CELERY_BROKER_PASSWORD”: “passcelery”, <— copy this password.
“CELERY_BROKER_USER”: “celery”,
List rabbitnq users
$ sudo rabbitmqctl list_users
Listing users …
guest [administrator]create user
$ sudo rabbitmqctl add_user celery passcelery <— paste the password
Creating user “celery” …set permissions for celery user
$ sudo rabbitmqctl set_permissions celery “." ".” “.*”
Setting permissions for user “celery” in vhost “/” …restart rabbitmq-server
$ sudo service rabbitmq-server restart
- Restarting message broker rabbitmq-server [OK]
we need to restart the apps
$ sudo /edx/bin/supervisorctl restart all
In, at least 2 documents, I found
sudo rabbitmqctl add_user celery celery
So, I coppied the line and because the second celery is the password and it’s not the same that in lms.auth.json and cms.auth.json the error didn’t solve.
I hope it helps.
