First, to clarify- this information only shows if you are doing the 4.10 version of the course (or earlier). If you do 4.12, the lab uses a dedicated cluster and the information required to access the cluster is included in the course.
I tried a 4.10 lab on RHU, and it's showing me the cluster details. If they do not appear for you, then you should open a support ticket- the support team has the ability to see under the hood and check what's happening to your lab environment.
(edit: also, as the thread is marked as solved- because the original poster got its solution, it might be easier to use a new thread.)
