Welcome to the Linux Foundation Forum!

I cannot connect to the master instance

I successfully created the first "master" instance and generated the SSH keys on my Mac, but when I try to connect to the instance, this is what I get:

➜  kubernetes-course ssh
The authenticity of host ' (' can't be established.
ECDSA key fingerprint is SHA256:BErL1ftY+YWnbFzb3rJx80qnu39QVjC6kNbKWcaeLpU.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '' (ECDSA) to the list of known hosts.

Can you help?

    No need to debug. I finally managed to fix the issue.

    Hi @msingh911,

    If following the infrastructure provisioning videos, then the ppk key file method is for windows users, and the pem key file is for mac and linux users.
