I assume your hub is connected via Ethernet cable to a router (possibly through a switch), correct?
If you look at your router's user interface, can you see evidence that the hub is connected and has an IP address?
How do you normally connect with the hub's UI? For example, http://192.168.1.60 in a web browser.
Can you tell if your rule (automations) are running properly even though you can't connect to the hub?
