There is a free network scanning app called "Fing". Does the bridge MAC address show up in this app (the bridge itself may show up as a "Texas Instruments" device)? If it does show up in this app, and you are still getting stuck on step 5, it could be that a port that the system uses to communicate with our server is getting blocked. See: https://forums.lutron.com/showthread...Networking-FAQ for a list of the ports that are used.
