I am a Newbie to Ansible , writing my first playbook. I can not SSH / PING to network Devices. ` leaf-1 | UNREACHABLE! =\> { “changed”: false, “msg”: “Authentication failure.”, “unreachable”: true } leaf-2 | UNREACHABLE! =\> { “changed”: false, “msg”: “Authentication failure.”, “unreachable”: true } i can PING / SSH to network devices from Ansible server but when i run the playbook , it fails. No idea if i have to add something in playbook or ansible.cfg . Any Suggestion please ? ` ---

First make sure ansible can actually sign in to the target hosts before trying to use roles. I’m guessing here but that role name indicates something related which might impact the connection. So best to start here: [https://docs.ansible.com/ansible/latest/user\_guide/intro\_getting\_started.html#connecting-to-remote-nodes](https://docs.ansible.com/ansible/latest/user_guide/intro_getting_started.html#connecting-to-remote-nodes) And then try something simple such as the a file or copy task. Once that works move on to more complicated things like roles. Dick ---
