Thanks have replied to the PM, have a feeliong my Hub is broken, swapped out my Firewall box and have went back to the ISP provided modem\router combo, I have the Hubitat wired into the one of the ethernet ports and a PC and a Phone connected wirelessly.
Still get the exact same issue, cannot load a page on the browser and unable to discover the hub.
Once thing I noticed is that when I check the time on the hub it is saying 2015
And the update time option doesnt seem to work, Really no idea what is going on here and never had a device that has been as troublesome as this, where do we go next @bobbyD
