Dell VxRail Deploy 2023 Simulator load unstable

Hi Dell Proven Cert Team,

Kindly be informed that during the simulation section, I encountered simulator loading issue with an error message "host/server not found'. 

For a workaround, I need to preview all 6x simulation questions and reset the simulator then only can load normally.

I feedback to the test center and they told me others also face similar issues and need feedback to Dell instead.

Kindly please need your attention on this matter to avoid the next candidates facing the same issue again.
