I'm glad it worked.
Just for your information:
Code:
PermitRootLogin without-password
does indeed mean that you don't need a password (even if one corresponds to the root user). But (even so it's not written there), it implies, that the client, that wants to login to the root account via SSH / SCP needs a valid certificate (or key) that was issued using the SSH servers private key. Of course, that needs to be preparated.
Logging in using the root user and don't need to provide a password or a valid certificate as default option would be a bit unsecure
With best regards
