+2Is everything on the same subnet or separate subnets, eg. Is your Nutanix Infra on the same subnet as your DNS servers etc?
If not, can you check if your firewall is blocking any network connectivity.
Have you opened a ticket with support?
+2There are guides out there on how to restart the prism service, you could try that, otherwise your safer option would be to engage the support and have them restore services.
