I noticed I could no longer connect to my VM's. I then logged onto my vCenter Server and saw that the ESXI Host was discounted. How did this happen? Did a NIC go bad or something? Both NIC's are blanking green.
This is in a lab environment. The only trouble shooting I've was reboot the ESXI Host. After that I still have this error. I still have 44 days left on my trail period.
Can you right click the host and select "connect"?
Also, try right click host "remove from inventory" then add it back in.
