Hello @Patrick Dhaene,
This error message is usually sent when a connection from UVC to the Dollar Universe Application Server is severed (example, a job runs view window is closed or UVC itself is closed).
Unless you are seeing the message repeatedly while actively using UVC, you can generally ignore it. If it does show up too often, there may be an issue with the network communication.
