I am trying to open Plesk Control panel from PVA power panel but it just show me the loading sign and nothing open. It takes too much time to open. what is the possible reason behind this issue? How can I solve it? there is no Change on plesk side, I have plesk 12.5.30 and windows server 2012 datacenter, it was working fast with virtuozzo 4.6 for windows, after upgrading to virtuozzo container for windows 6 the problem appeared, sometimes it works and sometimes it doesn't, So, if there is any Proposal for solution before submitting a Support ticket. please note that the plesk is not installed in containers using template, i have install plesk inside every container manually.
