Ansible fails to connect to host on some plays - ansible

Question

I have a very simple play that I'm having a lot of issues to get the run correctly. I keep getting an SSH unreachable error when it is run. I'm getting this on 2 separate machines in different environments (although built from the same images) These are Debian 9 boxes.
Play is to simply update an internal mirror server.
- name: Update Mirror Servers
hosts: all
become: yes
gather_facts: yes
tasks:
- name: Run Update
shell: "sudo apt-mirror"
- name: Change Permissions
file:
path: /var/apt-mirror
state: directory
recurse: yes
mode: '0755'
This is being run from Ansible AWX just in case that makes any difference.
Error is as follows.

I've tried adding the ansible_ssh_user and ansible_ssh_pass as variables on the group these machines are in.
I am able to run ping successfully etc.
Identity added: /tmp/awx_187_x0lo965h/artifacts/187/ssh_key_data
(/tmp/awx_187_x0lo965h/artifacts/187/ssh_key_data)
SSH password:
BECOME password[defaults to SSH password]:
redacted | SUCCESS => {
"changed": false,
"ping": "pong"
}
I'm sure it is probably something minor that I'm missing in config somewhere. Could someone point me in the right direction?
Thanks,
