Packer error while creating image for openstack using rhel base image

I am getting below error below error when trying to create image for openstack using RHEL base image.

I dont have any issue in creating a VM using the same base image via openstack console and cloud-user keys are getting added without any issues. Issue is only when I try image creation using packer

Error message from packer

openstack.rhel: Error waiting for SSH: 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

On the console of temp VM which was created by packer, i see this message

I have the same issue if I use centos base image, so it doesnt seems to be an issue with Base image.

Post your files, if you’re using multiple, setup a github repo and paste link.
