Hello group,

I would like to share this strange behavior.
PLAY [Update pi-hole servers] ************************************************************************************************

TASK [Gathering Facts] *******************************************************************************************************
ok: [zeropi.morelos.lan]
ok: [opizero.morelos.lan]

TASK [Update pi-hole] ********************************************************************************************************
changed: [zeropi.morelos.lan]
changed: [opizero.morelos.lan]

PLAY [Reconfigure DHCP to give both DNS servers] *****************************************************************************

TASK [Gathering Facts] *******************************************************************************************************
fatal: [zeropi.morelos.lan]: UNREACHABLE! => {“changed”: false, “msg”: “Failed to connect to the host via ssh: root@zeropi.morelos.lan: Permission denied (publickey,password).”, “unreachable”: true}
to retry, use: --limit @/etc/ansible/playbooks/pi-hole_update.retry

PLAY RECAP *******************************************************************************************************************
opizero.morelos.lan : ok=2 changed=1 unreachable=0 failed=0
zeropi.morelos.lan : ok=2 changed=1 unreachable=1 failed=0

This is the Playbook
root@monitor ~# cat /etc/ansible/playbooks/pi-hole_update.yml

Based on the above, some tasks succeed, and then after a task called
[Reconfigure DHCP to give both DNS servers], things break.
That would point to some problem there, where you may have locked
yourself out in some way that caused the
What that is, is for you to know - you haven't posted any playbook.

It´s a very small playbook.
