Farily new to ansible, so apologies if I’m missing something obvious.

Ansible version: 2.5.5

Issue: My task throws a hostname mismatch error when adding a new vhost on a server that contains a fresh installation of rabbitMQ:

`

- name: Ensure RabbitMQ virtual host exists  
rabbitmq\_vhost:  
name: “{{ item.name|slugify }}”  
state: present  
when: inventory\_hostname in groups[‘db-servers’]

`

Error description:

`  
fatal: [my-server-address]: FAILED! =\> {“changed”: false, “cmd”: “/usr/sbin/rabbitmqctl -q -n rabbit list\_vhosts name tracing”, “msg”: "Error:\*\*\*\*\*\*\*\*@localhost’

- home dir: /var/lib/rabbitmq
- cookie hash: pD9UkaDbh5qROT8GfbNTrA==",

Is SSL enabled on the rabbitmq server?

It’s a stock standard Ubuntu 18.04 server, all I did was install rabbitmq-server via apt. I have not changed any of the config files, so I’m assuming SSL is disabled by default.
