Cause

Se descubrió que el vProxy solo respaldará las VM ubicadas en el mismo host ESXi que él mismo. Si el vProxy intenta respaldar una VM ubicada en un host ESXi independiente, no se conectará en el puerto 902, como se muestra a continuación:
  
Could not connect to ESX host esxi_hostname: Failed to connect to server esxi_hostname:902.

Testing connectivity from the vProxy to the esxi host in question using the below command, hangs, and eventually fails to connect, though ping and nslookup, return expected results. 

#curl -kv esxi_hostname:902

Verified the firewall is down on the esxi hosts.

esxcli network firewall set -e false

Verified no layer2 firewall exists, or any firewall between the esxi hosts. 
 

Resolution

Se descubrió que todos los hosts ESXi se encuentran en VLAN de respaldo/administración independientes y no pueden comunicarse a través del puerto 902. Debe poder comunicarse a través del puerto 902 entre hosts ESXi y vproxy.
