VPS, plesk, virtuozzo problem

I I have VPS server with plask panel. But last 2 days I am not able to enter my domains, clients, resellers etc. When clicking on it it just shows "Plesk diagnostics" and empty page. Problem is probably this: I am getting the Plesk diagnostics page when I login to Plesk installed inside a container I need the fix now as I need to transfer new website to my VPS asap. Preferebly today. Fast work and fast payment.--- Symptoms When I login to Parallels Plesk Panel installed inside Virtuozzo container I am getting Plesk diagnostics page. Cause The issue is caused by the fact that fully qualified domain name (FQDN) of the container can be not resolved to IP by the service container. To verify it run this command on the node: vzctl exec 1 nslookup [login to view URL] where [login to view URL] is FQDN of the container. Resolution To fix the issue make sure that the service container has DNS servers configured in IP configuration of its network adapter and is able to reach the DNS servers. The most often misconfiguration is that the service container has automatically assigned IP which is not routed to subnet where DNS servers resided. To fix the issue it is necessary to enable NAT on the service container by using this command: vzctl set 1 --nat on --save
