SSH handshake failed


I am getting this error when I get the AMI-ID from ova.

amazon-ebs: Packer experienced an authentication error when trying to connect via SSH. This can happen if your username/password are wrong. You may want to double-check your credentials as part of your debugging process. original error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain.


Any help is greatly appreciated

Thank you!
