Unreachable error

[navdeep uniyal]

Hi all, 

I am new to ansible. I have been learning ansible using ad hoc commands as well as ansible playbooks. Things were running fine until I started getting errors as given below. I have no idea how to resolve these errors. Please help.

navdeep@ansible-master:~$ sudo ansible all -m ping -s -k

SSH password: 

127.0.0.1 | UNREACHABLE! => {

    "changed": false, 

    "msg": "Authentication failure.", 

    "unreachable": true

}

navdeep@ansible-master:~$ sudo ansible-playbook our-playbook.yml -s -k -K

SSH password: 

SUDO password[defaults to SSH password]: 

PLAY [local] *******************************************************************

TASK [setup] *******************************************************************

fatal: [127.0.0.1]: UNREACHABLE! => {"changed": false, "msg": "Authentication failure.", "unreachable": true}

to retry, use: --limit @our-playbook.retry

PLAY RECAP *********************************************************************

127.0.0.1                  : ok=0    changed=0    unreachable=1    failed=0

First, check SSH connection. In your case:

ssh 127.0.0.1
