The check port 22 to be available is done in remote host

[juan-cabrera]

Describe the bug

The following task is executed on managed hosts (remote host)

- name: Wait for port to be available
  ansible.builtin.wait_for:
    port: "{{ ansible_port | default('22') }}"
    timeout: "{{ bootstrap_timeout }}"
  become: false
  when:
    - ansible_connection is defined
    - ansible_connection not in [ "container", "docker", "community.docker.docker" ]
    - ansible_connection is not none
    - bootstrap_wait_for_host

With default port value 22 I get

TASK [bootstrap : Wait for port to be available] *******************************
│ fatal: [dev064]: **UNREACHABLE**! => changed=false

when the managed host (a VM) is still booting, port 22 is not yet open, so the task fails and the playbook stops. The bootstrap_timeout is not taken in to account in this case.

In ansible documentation the way to check SSH availability is using local connection

# Do not assume the inventory_hostname is resolvable and delay 10 seconds at start
- name: Wait 300 seconds for port 22 to become open and contain "OpenSSH"
  ansible.builtin.wait_for:
    port: 22
    host: '{{ (ansible_ssh_host|default(ansible_host))|default(inventory_hostname) }}'
    search_regex: OpenSSH
    delay: 10
  connection: local

# Same as above but you normally have ansible_connection set in inventory, which overrides 'connection'
- name: Wait 300 seconds for port 22 to become open and contain "OpenSSH"
  ansible.builtin.wait_for:
    port: 22
    host: '{{ (ansible_ssh_host|default(ansible_host))|default(inventory_hostname) }}'
    search_regex: OpenSSH
    delay: 10
  vars:
    ansible_connection: local

Playbook

Please paste the playbook you are using. (Consider requirements.yml and
optionally the command you've invoked.)
