Virtual machine console connection error in Intelligent Infrastructure environment

When connecting to the console of a virtual machine in the II environment using VMware's Virtual Machine Remote Console (VMRC) version 11 or newer, you may encounter a connection error.

VMRC connection error

The error occurs because of a port change that VMware implemented in VMRC version 11; the workaround recommended for this change became unsupported with vSphere 8.

To resolve this issue, undo the modification to the preferences file on the client system attempting to connect to the VM console as VMware described in the "Resolution" section of this article.

You will need to change the two lines to the following:

pref.preferWebMKS = "TRUE"

pref.preferWebRemoteDevice = "TRUE"

Note:

This is required only on clients that applied the previous workaround and only for connections against vCenter directly. The VMRC client is no longer used if you are accessing the VM console via the Intelligent Infrastructure self-service portal.
