to Packer

We have been using packer for a while it use to work with older version of 1.6.6 but with the latest version we were are getting error once we went through different channels issue is ssh go communicator is no longer supporting so we started using ed25519 keys.Connectivity is through bastion host we are using hashicorp ssh certificate proces.

Providing SSH private key and also ssh certificate but we are getting below.Clearly my local mac is able to connect to bastion jump host but from jump host its not connecting.
