Task create sshd_config and set permissions fails

[magick93]

Describe the bug

I'm getting the below error on create sshd_config and set permissions to root/600 which I think is this task.

Expected behavior
Expect the playbook to complete successfully

Actual behavior

See above

I think this was caused by using ssh_listen_to: "10.8.001.0" rather than using an array.
