please advise what is the fix for this, I have just lost access to 14 vps running hyperv core and cant manage these servers now that I have upgraded to version 1.4.3.  I need help urgently now to fix this issue.

TechGuy - i think your problem is different from my problem posted above - my problem is not fixed but it is related to Hyper V Provider For Private Cloud - i guess you are not using this
