Doing the Get Started setup process with my new hub. Everything was going great until the firmware update. I've been stuck on this screen for an hour that says, "Rebooting
Hub reboot in progress. This should take 2 minutes or less." The light is solid green
You should assign an address reservation in your router, so it always gets the same address. This is also true of any home automation device like Alexa. If the address changes, it can mess up the link between devices.
I also would suggest bookmarking the hub IP address (192.xxx.xxx.xx) so you can get back to it easily.
New Incognito tab worked for me as well. I tried from my PC in Chrome first and that did not work. Only incognito on my phone would make me continue setup. Didn't want to reboot and mess up the process unless I had to. Thanks guys!!!!
I would also like to say Thank You, for the Chrome Incognito advice.
Starting from the "getstarted.hubitat.com" page in the Google Chrome Incognito screen, provided smooth installation results; compared to being stuck on the Reboot screen that I was in before.
If you changed the IP then it will never reconnect to the old IP. I did the same thing and it took me a minute to realize I was still trying to reconnect to the old IP. This will also happen if a new Ip is assigned through your DNS. Go to the search at the bottom left. Enter cmd then hit Enter. At the DOS (black screen) type arp -a. Look for a MAC starting with 34-E1. That should be the Hubitat hub address.
