Unable to connect to the server: EOF

I just build my environment, everything shows as "Active", but I'm getting this error.

It's working now, maybe there were so backend processes that were taking longer than expected

That makes sense! Sometimes backend processes or services can take longer to initialize, especially if the OpenShift API server or other components are still starting up or there’s temporary network latency. Glad to hear it’s working now!

@MikeInAZ When you create a fresh lab or just restart your lab, even though your VMs show active, the OCP cluster is not yet ready. It takes some time to get ready with all its components before you can send requests to the API.

There is a wait time of 20-30 minutes for the cluster to be ready. Please don't execute any lab script while cluster sync process is running. Even if you restart your VMs , check if the cluster is ready or not before starting with the labs.

You can check if the cluster is ready or not by following the below commands - 

1. ssh to the utility VM as lab user - ssh lab@utility   ( from workstation )
2. On the utility VM , run the command - " ./wait.sh --wait " . Wait for the script to finish running . Once all the components are ready, you can start with the lab start script on the "workstation" VM.
