I ran into an issue recently that was surprising at one location. While the computer running Concert and UpdaterAtor were on the same VLAN/Subnet as the CEM+ Dimmer Controllers, and could ping each other and access the website GUI, neither Concert nor UpdaterAtor would see these devices. It was discovered that the CEM+ had an incorrect network router in the configuration. Which from a networking standpoint would explain why you would not be able to traverse between subnets, but it would seem that the router defined on the CEM+ host shouldn't impact the discovery protocol as that should all occur on the local network/broadcast domain. Thoughts?
