Based on the output it appears that Ansible is able to reach the device just not able to authenticate.
I say that because you get the line: > "msg": "Authentication failure.", Where as if Ansible was unable to reach the device at all I would expect something like this: "msg": "Failed to connect to the host via ssh: ssh: connect to host 10.0.1.45 port 22: Operation timed out", Do you have all of your connection variables for the networking device properly set?
