I completed this task yesterday and it was marked as failed upon finishing it. I had made sure to the best of my abilities that all the required rules were in place and persistent upon reboot. Please could you review this and let me know if the problem was indeed on my side?
FYI One weird thing though was during the 5 min allowed to make screenshots, I somehow could not access any of the machines, due to an error about wrong password… even though I was using the same passwords I used minutes before to configure them in the first place. Bug maybe ?
