Troubleshooting kubespray offline for Ubuntu 20.04

Cluster information:

Kubernetes version: v1.22.1
Cloud being used: bare metal (hyper-v)
Installation method: Kubespray, offline
Host OS: Ubuntu 20.04
CNI and version: calico latest (v3.2?)
CRI and version: Docker 20.10.8

I’m attempting to deploy Kubernetes (ubuntu 20.04) on a private LAN using Kubespray.

I have an internal docker registry and repo/file service available.
The nodes have been prepped and are accessible.
Kubespray runs successfully through the docker install and dies shortly after with the following:

task path: .../kubespray/roles/download/tasks/download_file.yml:52
........
Failed to connect to the host via ssh: <error censored due to no log>

I’m guessing my trouble is in the offline.yml.
Are there working examples of the offline.yml for Ubuntu 20.04 ?

I’m using the switch -vvvv but the error message is a little cryptic.
Is there a way to determine what task is failing?

Edit download_file.yml and comment out no_log: true like this: #no_log: true. Run the play again.

kubernetes-sigs/kubespray/blob/master/roles/download/tasks/download_file.yml#L52-L71

    
      
          - name: download_file | Download item
            get_url:
              url: "{{ download.url }}"
              dest: "{{ file_path_cached if download_force_cache else download.dest }}"
              owner: "{{ omit if download_localhost else (download.owner | default(omit)) }}"
              mode: "{{ omit if download_localhost else (download.mode | default(omit)) }}"
              checksum: "{{ 'sha256:' + download.sha256 if download.sha256 else omit }}"
              validate_certs: "{{ download_validate_certs }}"
              url_username: "{{ download.username | default(omit) }}"
              url_password: "{{ download.password | default(omit) }}"
              force_basic_auth: "{{ download.force_basic_auth | default(omit) }}"
            delegate_to: "{{ download_delegate if download_force_cache else inventory_hostname }}"
            run_once: "{{ download_force_cache }}"
            register: get_url_result
            become: "{{ not download_localhost }}"
            until: "'OK' in get_url_result.msg or 'file already exists' in get_url_result.msg"
            retries: 4
            delay: "{{ retry_stagger | default(5) }}"
            environment: "{{ proxy_env }}"
            no_log: true
