I ordered my C8 on March 1st, 2023. After the initial configuration it has been fine. I added a couple additional devices a few months ago and it was working properly. However, the other day I used the app on my android phone to pull up the dashboard. It was so slow and unresponsive. I then went to my computer. I pulled up the static IP on a browser and it was slow also. I used the webpage to have the C8 reboot. That was the last I have seen of my C8. It now has a constant blue light and will not respond to its IP address. I used findmyhub.hubitat.com. No luck just scanning. Then I typed in the MAC address. It did find it but when I click the "connect to my hub" button it cannot load the page. It was plugged into a UPS the entire time. I have also put a different wall wart and USB cable but it had no effect.
Yes. I held it for 10 seconds. Blue light went away. Green light appeared for a second or two then went blank. Red light appeared for a second then when blank. Finally, blue light came on and is still on steady.
I'm not sure I would say the router changed it. I statically / manually assigned the C8 to .30 when I first configured it. The only reason it is .179 now is because I was told to perform a "network reset" on it, which must have wiped the settings and put it back to DHCP, The only reason I didn't search for a new IP address earlier was because the "findmyhub" tool was still reporting it as the static .30
Do manual backups to your pc once in a while. Get Hub Protect, this will back up not only the database but the radios to the cloud in case it ever has to be replaced and it's basically an extended hardware warranty. And by all means, yes, update to the latest platform (download a current backup to your pc when prompted)
As to it coming out of the blue. It can happen. Brownouts, power disconnects (without shutting down properly) are big causes.
