I again ran into switchboard not picking up the livelink data. This was a hard one to solve – but since the live link data was working on the camera in the editor, just not in switchboard, I knew it was a connectivity issue and stumbled on a post that pointed to the IP address as a likely culprit. In short, do NOT use the loopback IP (127.0.0.1) and instead using the actual IP of the machine. Sharing the link that had the solve and a
video showing the places where I changed the IP address.
