Connection attempt from node rabbit_ctl_46@ubuntu rejected. Invalid challenge reply

[Brady Harper]

I've currently got Minikube setup on my host machine with a RabbitMQ cluster operator installed and deployed. I have a script that sends messages from the host machine to Minikube, however when I run it I get the error:

"Connection attempt from node rabbit_ctl_46@ubuntu rejected. Invalid challenge reply"

My deployment YAML file is:

apiVersion: rabbitmq.com/v1beta1

kind: RabbitmqCluster

    storage: 5Gi

The cookie being copied over is definitely the same as the one on the host machine (I verified it using the Minikube dashboard), what else could be causing the connection to be refused?
