[Users] What parameters to use in automated node install to enable engine CLI register?

Hi Itamar,

Happy New Year!

My host can actually be added manually. However it's status is "Non Responsive".  I put it into "Maintainence" and "Activate" it again without any success.  Any idea how to debug the problem with a stateless host?

David
