Today we’re going to talk about Ansible troubleshooting and specifically about connection failed errors. I’m Luca Berton and welcome to today’s episode of the Ansible Pilot. The root cause of these types of problems rely directly on the networking. So jump on the ssh command line and troubleshoot like an ssh connection error. In the following example the Operation timed out was caused by the virtual machine that doesn’t have network card enabled.


The best way of talking about Ansible troubleshooting is to jump in a live demo to show you practically the connection failed error and how to solve it!


Ansible relies on an SSH connection to the target machine. Let’s try manually:

$ ssh username@hostname
Failed to connect to the host via ssh: ssh: connecto to host hostname port 22: Operation timed out

You need to verify the network connection between the source and the target machine.


Once the network connection is fixed you could successfully connect to the target machine.

$ ssh username@hostname
