I had a fresh install of XWS version 5.6.3, licensed for Mobile Print and Print Management workflows. I have adequate workflow connectors (12) and am trying to add a VersaLink C605 and VersaLink C405. The printers are discovered automatically by my discovery profile, however they are enabled with errors. The main errors (red x) are for Authentication and Accounting. They both give the error saying "Online activation failed: There was an error processing your request or the system was busy. Please try again later." My server is able to access the internet, as a my MFPs, however I cannot seem to get these licensed features to enable. I have tried connecting one of these devices to a Workplace Cloud Company and they connect with no issues so the problem seems to be with the XWC deployment/settings.
I have tried:
Disabling, deleting and re-adding the MFP
Adjusting Login/Logout setting on the MFP (to enable convenience authentication)
Upgrading Prerequisites and Workplace Suite to latest version 5.6.6
