Description: SSH to lab VM is not working as described in the instructions.

Per instruction ssh into lab does not work.
=======================================
kneal@fedora:~>ls ~/.ssh/
config id_rsa id_rsa.pub known_hosts known_hosts.old rht_classroom.rsa
kneal@fedora:~>ssh -i ~/.ssh/rht_classroom.rsa -J cloud-user@52.118.50.195:22022 student@172.25.252.1 -p 53009
ssh: connect to host 52.118.50.195 port 22022: Connection refused
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535

Connection via jump host looks to be the issue.
Also if open workstation (VM ) via console(browser) and check IP address I see it as 172.25.250.9. Should SSH to that VM. I am getting same results because issue looks to be with the "jump" host.
