C-8 Became unresponsive and stuck in blue LED mode

My C-8 suddenly stopped communicating a few days ago and I only get the blue LED when I re-boot. If I do the 8 second reset, the LED briefly blinks green then blinks red then goes back to blue. I was going to run the diagnostic tool by entering the former ethernet address with:8081, but got nowhere there either. I'm not sure what to do if I don't have the right ethernet address for that matter. I would love some hep.

Thanks,
John

Does the hub show up in your router DHCP list? Have you gone to my.hubitat.com and checked what IP address was last time the hub checked in?

Thanks for the ideas. I had forgotten about my.hubitat. I just tried that and still got no response from the most recent Ethernet address.

I'm not sure how to access the DHCP list from my Cable model. I assume that is where the DHCP list would reside.

Thanks,
John

Do you have access to your cable modem dashboard ?

You can try the find my hub page: https://findmyhub.hubitat.com/ and the advanced options.

Or if that's not working you can try this tool https://angryip.org/ to scan the entire LAN

You may also want to try a network reset on hub using the hidden button on the bottom of it, as shown in the docs here: Network Setup | Hubitat Documentation

I do not have access to the modem's dash board. I may try to see if I can get it.

Thanks for those great links. I tried the MAC scan and the in findmyhub as well as the Ethernet scan but no luck. It's unclear if angryip.org works with Windows. I says it does in the description but it does not have that selection in the OS field. I only see Ubuntu, Debian, SLES, Red Hat, Docker and VMWare ESXi. Does one of those work on Windows?

I did try the hidden reset early on and it goes to blue, then green blink then red and then permanently back to blue.

Thanks,
John

The windows installer is on their website:

https://angryip.org/download/#windows

I agree that trying to confirm if your hub is currently on the LAN is the next step.

If you can locate it then you can attempt to login to the diagnostic tool to do a soft reset on the hub.

I see your point, their download page is a little confusing, took me a minute to find the windows link.

Or also on Guthub

Thanks for the Windows link everyone. I got AngryIP installed and scanned the net. I have a lot of things on my home network but believe I found the hub and it matched the IP address that my.hubitat.com listed as recent, but it is unresponsive to opening a web page there. I can ping it though and obviously it responded to AngryIP so it's not totally dead, but it does not seem to be booting all the way. I actually have 2 Hubitat's on my network and I can get access to the other one no problem, but my primary Hubitat C-8 is still unhappy.

Any ideas on how to breath some life into it now that I found it?

Thanks,
John

Connect to port 8081 (diagnostic tool). Not the default port 80.

Yes, of course. Thank you! That did work and I can get to the diagnostics page! Excellent. I'll download some backups, try a re-boot and then maybe update to latest SW version

Download backups. Do a soft-reset. Restore your most recent backup.

Thank you all. That worked and the Soft Reset to an older backup works. Thank you very much for spending your valuable time assisting me. Very much appreciated.
