Just got 2 units XT8 and after initial setup update popup so I decided to run it. Well that was a mistake. After update my main node stop working. only keep showing solid "blue" light and no matter what and how I did can't pass initial setup anymore. it just stuck with "connect your router" even cable connected and everything is working fine. I already reseted and still not able to setup node. as right now I reseted second node and setup it as main. Do you guys know what I can do? or only option would be send it back?
