Cannot add Virtual Center to vRanger inventory (4035412)

Cannot add Virtual Center to vRanger inventory

On a new vRanger install, the install of the application completes, but the Virtual Center and/or ESX(i) Hosts cannot be added to inventory. No error is displayed, but all connection attempts fail. Browsing to the VC's or Host's Managed Object Browser (MOB) via a web browser on the vRanger machine also never connects (the address of the MOB is https://{VC or Hostname}/MOB).

Certain "locked-down" environments may have some sort of  pro-active Intrusion Protection System (such as HIPS) active on the network. These devices (software or hardware-based) may be blocking the attempts by vRanger to connect to the Virtual Center via port 443 (SSL).

vRanger must be able to connect to the Virtual Center or Host machine(s) (if not using a VC) on port 443 (SSL) to verify credentials and add the item(s) to inventory. Things to check if some sort of "port-blocking" is enabled:

1) Verify no firewalling exists between the vRanger machine and the VC/Host(s) (including VMware's firewall settings, defined in the "Security Policy" section of each Host machine's "Configuration" page, and also the Windows Firewall/other filtering software on the vRanger machine itself).

2) If no firewalling exists, and a HIPS-type system is installed on the network, ensure that the Intrusion Protection System is allowing the port 443 traffic to-from the vRanger machine and the VC/Host machines
