Ansible hangs on user input expectation when running in serial / forks

The options at the bottom (serial and forks) hangs the whole process if there’s one server that is waiting for user input for some random reason (change password, authenticity of host can’t be established as two examples)

Is there anyway to get past this hangup ?

i’ve tried ignore_errors: true and ignore_unreachable: true

Are these even needed ?
(they are trials that seem to increase speed in running the ansible user management script against a 75 or so servers… )

  • name: “Add or remove users”
    hosts: tag_ansible_managed_true
    serial:
    • 10
      become: true
      gather_facts: true
      strategy: free # noqa: run-once[play]
      roles:
    • amazon_user_accounts

and in ansible.cfg
forks=10
