[SOLVED] Port 22 timeout when ping EC2 with Ansible

Issue

I'm working off WSL2 and a small EC2 instance with RHEL-9.3.0_HVM-20231101-x86_64-5-Hourly2-GP2 AMI. Purpose is to learn Ansible.

When ssh my instance from WSL, all works fine and connection is established

ssh -i "my_keys.pem" [email protected]

However, when running:

ansible all --key-file ../my_keys.pem -i inventory -m ping

I'm getting an error:

xx.xx.xx.xx| UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: ssh: connect to host xx.xxx.xxx.xx port 22: Connection timed out",
    "unreachable": true
}

Double checked following:

• Ansible's config
• EC2 ports and allowed IPs

Here is output using -vvvv:

Thanks for any suggestions!

Solution

inventory file, in case of EC2, required Public IPv4 DNS format.

ansible_user can be helpful also to skip passing it with cli -u parameter.

ec2-xx-xxx-xxx-xx.region-number.compute.amazonaws.com ansible_user=ec2-user
