Unable to connect to the MKS: Failed to connect to the server servername:902

“Unable to connect to the MKS: Failed to connect to the server 172.16.254.202:902” or “Unable to connect to the MKS: Failed to connect to the server no such host is known”

Solution:

To avoid losing access to the ESX host, perform the following steps:

1. Add the ESX server in your DNS

2. Edit your hostfile on the workstation (C:\Windows\System32\Drivers\etc\hosts\) and add your ESX server

After adding the ESX by DNS in my hostfile and restarted the VI Client I was able to open Console screen.
