Hello,

the following ansible 2.1.1.0 command hangs:

It's hanging on sftp, so it can't copy the files it need.

An Ansible ping is not the same as ICMP ping. Ansible ping is checking
Ansible functionality.

You need to check why sftp is not working aganst the node.
Try copy files manually with sftp. Check you OS logs for error message.
