Connection failed - Ansible troubleshooting

Connection failed errors are one of the most common Ansible problems. In a live demo, we are going to troubleshoot starting from the error message. We are going to investigate the root cause of the problem and fix it.

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 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 [email protected]
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.
