Overview of the Issue
Getting the below ssh error during the packer build process, similiar to #6341.
Reproduction Steps
packer build --force build.json
Packer version
# packer version
Packer v1.5.4

Please note that SSH into a VM instance created with the same image manually works just fine.
Also using the second latest image centos-8-v20200309 with packer works fine aswell.
Any guidance would be appreciated.
