Ansible ssh connection closed error

Problem:
Ansible returns the error "Failed to connect to the host via ssh: Shared connection to host closed"


Solution:
Modify ansible.cfg to send a SSH keep-alive ping every 2 minutes.

ssh_args = -C -o ControlMaster=auto -o ControlPersist=60s -o ServerAliveInterval=120
