Hi,

I am having a problem running the ansible -m ping command.

The error that I am getting is UNREACHABLE, but this is silly as plain ssh [ubuntu@ec2-11-222-111-44.compute-1.amazonaws.com](mailto:ubuntu@ec2-11-222-111-44.compute-1.amazonaws.com) works.

When a add -c paramiko the ping commands also works.

I am using Mac OS X Sierra and ansible v2.1.2.0.

(I changed the hostnames below…)

What is going on and am I doing something wrong?

P
