Nagios play fails

[Dimitri Yioulos]

I'm trying to quiet Nagios alerts after a Windows update, but before reboot.  I call the playbook like this:

ansible-playbook -l ws0 win_updatelyrisserversB.yml (with or without -u)

Here are the relevant parts of my playbook:

- hosts: all

  gather_facts: false

  tasks:

    - name: win update

      win_updates:

        category: ['SecurityUpdates','CriticalUpdates','Updates','Tools','DefinitionUpdates','UpdateRollups']

      register: reboot_hint

      tags:

         - update

- hosts: all

  gather_facts: false

  sudo: yes

  tasks:

    - nagios: action=downtime minutes=5 author="Dimitri Yioulos" service=host host={{item}}

#      with_items: "{{ play_hosts }}"

#      with_items: "{{ groups['lyris'] }}"

      with_items:

         - ws0

      delegate_to: admin2

#      when: hostvars[item]['reboot_hint']['reboot_required']

#      when: ['reboot_hint.reboot_required']

      tags:

         - nagios_downtime

    - nagios: action=downtime minutes=5 author="Dimitri Yioulos" service=all host={{item}}

#      with_items: "{{ play_hosts }}"

#      with_items: "{{ groups['lyris'] }}"

      with_items:

         - ws0

      delegate_to: admin2

#      when: hostvars[item]['reboot_hint']['reboot_required']

#      when: ['reboot_hint.reboot_required']

      tags:

         - nagios_downtime

- hosts: all

  gather_facts: false

  tasks:

    - name: reboot server

      raw: 'cmd /c shutdown /r /t 0'

      when: reboot_hint.reboot_required == true

      tags:

         - reboot

The Nagios play fails like this:

TASK: [nagios action=downtime minutes=5 author="Dimitri Yioulos" service=host host={{item}}] *** 

fatal: [ws0 -> admin2] => Authentication failure.

FATAL: all hosts have already failed -- aborting

As you can see from the commented out parts of the Nagios play, I've tried several things (many not shown) to try and make this work, if even possible.  Can anyone help?

Thanks.
