Having this error message trying to open a virtual machine (guest) console?

The VMRC Console has Disconnected. Trying to reconnect

This is probably because either your host or vCenter server does not have the necessary ports opened or filtered. You should have the following port opened on the firewall :

tcp-443
tcp-902
tcp-7331
tcp-9443 (vCenter WebUI only)
