When I try to open the console of a VM I connect to from vSphere client I get the error

"unable to connect to the MKS: Failed to connect to server 10.10.20.48:902".

When I connect to the same VM from vSphere Client installed on another machine it works fine. Or if I restart my machine and try it works. The issue occurs once in two or three months. Why is it so??

attached is the screen shot for clear description

Disable the firewall ?

The Console, is displayed via modified VNC, via Port 902.

telnet <ip address> 902

where IP Address is the ESXi server ?

do you get a connection?

check and connect via IP Address.

also check you can resolve the Hostname via DNS, or create a hosts file entry.

Hello Andrew,

Was away on a visit to a client.. and so the delayed response... The telent will not work as we have disabled the access.

will that be an issue.?

Telnet provides you with a quick tool, to check if port 902 TCP is open on the server.

What OS is your workstation running?
IS AV installed?
Are you using a Wired or wireless connection?
Any error in the event logs on your workstation when the issue happens
Have you tried to run a packet trace using wireshark or Network monitor to monitor your vsphere client connection to the host?
If using a wired connection, and port errors on the switch your workstation is connected to?

If you have disabled telnet, what other firewall ports have been discontinued.

Can you DISABLE you firewall.....

If the issue repeats every couple of months I suggest you install monthly microsoft patches and never face any issue again.
