Found the answer via phone service from Wyse. KB #22691 on Wyse documentation.
With the release of firmware version 7.1_122, the VNC server was disabled as the default option, and security was enhanced requiring the upgrade to WDM 4.9.1 to manage WTOS-based thin clients from this version on.
To enable the service, add the following line to your WNOS.INI file:
Service=vncd Disable=No
VNCPassword=
VNCPrompt=No
