Have you had some sort of power outage that caused your router to reboot and maybe allocate your hub a different ip address?
What hub is it. C3, C4, C5, C7?
Mind you I suppose it should still be found by the portal.................
Portal is currently not working in Chrome on Windows 10 and Chrome book as I understand it. You may want to try another browser. Strange that your hub has a red LED even when things are functioning.
And just to add in.. the LED is still red.. It always is actually. Should I contact support about this then? The hub is definitely up and running... I mean I have lights going on and off all over this place... but the LED light... is red.
Personally I wouldn't do this because as @aaiyar has said, some older hubs have had issues with the LED but everything is OK, hence my question, what hub is it.
