Installation of VM Essentials manager fails with an exception "No route to the host"

[SathyaNarayanS]

Hello Everyone,

I am trying to set up a Morpheus VM essential Lab on top of the existing vsphere environment. Installed the ubuntu hosta nd completed the installation of the VME console using the latest available software , VME Essentials manager installation fails at 99% with an error " No route to the host". I see am not able to reach the IP address assigned to the manager from the host however Unable to figure out why it is failing. Can someone help me to identify what am I missing in this configuration?
