File copy fails with large file

Archives Ansible Project
1

Outside of Ansible, the user ansible can scp the file in 52 seconds.

Using Ansible, even after upping the timeout to 105 seconds per https://github.com/ansible/ansible/issues/14426

the copy fails with:

fatal: [psalms]: FAILED! => {“failed”: true, “msg”: "Timeout (105s) waiting for privilege escalation prompt: "}

Changing the playbook to copy a smaller file, the CentOS-6_minimal.iso, works.
