k3s-agents fail to start due to being unable to grab the CA certs

[brandon-dacrib]

I am running on arm64. My ks3-agent instances all fail to start with the following error: I get

level=error msg="failed to get CA certs: Get "https://127.0.0.1:6444/cacerts\": EOF"

When I hop onto one of those nodes and run

````curl -k -v https://127.0.0.1:6444/cacerts I get

curl: (35) error:0A000126:SSL routines::unexpected eof while reading.

I am running on some turing pi rk1s and my inventory.yml looks like
`

Check your firewall on the nodes. Are you blocking communication over port 6444. This is likely not an issue with k3s-ansible, its a problem with the communication between your nodes.
