      Issue description

      Cluster is not getting synced for DO240 course, its stuck at Waiting for API....

      Tried many times re-provisioning the lab but still the same.

       

      Steps to reproduce:

      Create a new lab environment 

      Workaround:

      Create the following bash script on the workstation and execute it to set the date back:

      #!/bin/bash
      # SSH into "utility" and run commands on each target node
      ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null lab@utility << 'EOF'
        for node in 192.168.50.10 192.168.50.11 192.168.50.12; do
          echo "Running command on $node..."
          ssh -i ~/.ssh/lab_rsa -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null core@$node "sudo date -s 'Thu Feb 13 11:34:49 UTC 2025' && sudo systemctl restart kubelet"
        done
      EOF
      

      Note that this workaround must be re-applied if the environment is rebooted or if the environment is shutdown (or auto-stopped) and started again.

      Expected result:
