msg: 'Failed to connect to the host via ssh: kex_exchange_identification: Connection closed by remote host' about action-ansible-playbook HOT 4 CLOSED

This doesn't look like you have an issue with this action, it looks like you have an issue with your SSH key configuration. In the code you shared you don't even call the action that @dawidd6 made.

If I were you I'd look into the keys you're using and the sshd configuration (/etc/ssh/sshd_config) on the host you're trying to connect to.

@clincha Thanks for your reply. You're right, I didn't share the whole of the github action- I've edited the gist to include this.

The other weird thing is, as you can see in the updated action, I do a manual ssh to the box in question and I can report that this works fine.

Here is more context around the error arisiing in Ansible:

Can you cut out everything except for the ansible step and check if that works? Also remove the known hosts stuff please (try to get the minimum working then build from there).

'IdentityFile="/home/runner/work/flawless-infra/flawless-infra/ansible/chubb/.ansible_key"'

It seems to be passing in the key correctly. Can you please post your ansible.cfg file or however you pass in your Ansible environment.

I still get the feeling that this isn't an issue with this action but an issue with the key or the server itself

No response. Closing.
