SSH encountered an unknown error during the connection - Ansible Error

Question

I'm running ad hoc ansible tasks instead of adding them in a playbook, but I get this error:

default | FAILED => SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue

What is the issue?

Answer 1

I think you have not configured your ssh yet. You can do it by executing the following command:

ansible all -i vagrant_ansible_inventory_default -u vagrant --private-key ~/.vagrant.d/insecure_private_key -m ping
