Here is the response you're waiting for 
But first, why would you have regrets if the hub has been working fine for the past few months? Usually a hub with a hardware issue will simply not work consistently. An intermittently working hub is more so indicative of local environmental issues. The "No response from hub" message points to network issues. We often see this happen when customers are trying to connect to the hub from a mobile device that is connected to a cellular network. To resolve that problem the user needs to make sure that the mobile device and the hub are on the same network segment.
If you believe that this is not a network problem, or if you'd like to make sure that you are not dealing with some kind of hardware malfunction, please send me a private message along with your hub ID and I'd be glad to further assist.
