Based on your other posts, your hub was already set up and you were able to reach it since you mentioned you've added the first devices. Something to keep in mind, some of the suggestions in this thread assume that you are just trying to get started. Please be sure the device you are trying to access the hub is connected to the same network as the hub. You may not need to make any changes to your network since you set up the hub and was working at some point.
