Ssh – Ansible throws an error with SSH connection reset when used under cygwin

ansiblecygwinssh

When I try to do anything, even something basic with ansible under cygwin, I get the following error:

$ ansible all -m ping
example.org | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: mm_send_fd: sendmsg(2): Connection reset by peer\r\nmux_client_request_session: send fds failed\r\n",
    "unreachable": true 
}

Add the following lines to ansible.cfg (either in the playbook folder or in /etc/ansible/ansible.cfg):

[ssh_connection]
ssh_args = -o ControlMaster=no

From what I've gathered, ControlMaster=auto also works, but under cygwin this option has to be disabled. Source.
