Postal_worker 1 keeps stopping

[TheLazyHatGuy]

I have tried changing the version of RabbitMQ I am running with Docker and I have tried using commands like

$ rabbitmqctl set_user_tags YOUR_USERNAME administrator
$ rabbitmqctl set_permissions -p / YOUR_USERNAME ".*" ".*" ".*"

With no luck.

I keep getting the following error

cron_1      | E, [2021-08-29T15:53:41.184625 #9] ERROR -- #<Bunny::Session:0x55686ba004a0 [email protected]:5672, vhost=postal, addresses=[127.0.0.1:5672]>: Authentication with RabbitMQ failed: 403 ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.

Any advice?
For reference, I followed this guide: https://docs.postalserver.io/install/installation

You might have to scrap the rabbitmq and start again, making sure to specify the credentials when the container is run for the first time

https://docs.postalserver.io/install/prerequisites#rabbitmq

If you run it without that information and persist the volume then you would have problems like these

I did it exactly as detailed in that guide but it never worked

[willpower232]

have you definitely fully deleted the rabbitmq container and made it again?
