I have three hubs. One of them is in Florida and is a C-8. The other 2 are located on the same property but are in different buildings ("cabin" and "barn") and on separate routers. These are both C-7 models. I am currently at the property that has the 2 C-7 hubs. The cabin hub I can connect to locally and through Hubitat.com. The other two I cannot connect to. When I go to the barn it will not connect locally and I cannot reach it through remote administration (it says "offline"). The C-8 in Florida I cannot reach through remote administration (It also says "offline").
Any thoughts or suggestions?
