I just updated to the latest firmware as I've done many times, I've been running Hubitat for years, upgraded to a C8 Pro last year. It became unresponsive for over an hour, I did a hard reboot, to try and bring it back but it's still unresponsive. the light is green. I don't have access to the diagnostic tool either. How do I restore this?
Going to need to answer some of the questions stated in that post you linked.... particularly the ones about static IP and/or reservations.
If the light is green, it should be connected to the cloud. I am thinking you have a situation where the IP address has changed on you. Also, describe what a "hard reset" means to you. If you just unplugged it, there is the possibility that you corrupted the database.
All Hub Issues
- Model of Hub
- Platform/firmware on hub
Connection / Goes Offline
- How is it connected to the LAN?
- Ethernet / Wifi
- Static IP set on Hub or DHCP?
- DHCP Reservation set on Router/Server?
- How is Hub being powered? Supplied power block or other (explain)
- Brief explanation of network topology.
- Brief explanation of firewall / DNS / DHCP services.
- Is Jumbo Frames enabled anywhere on the LAN?
- How many devices total (approx) and mix between Zwave, Zigbee, LAN/Wi-fi
- What user / custom integrations are you using for LAN/IP/Cloud based connections?
- Screenshots of Past Logs from the incident, and also of any errors being generated recently.

Green usually says the UI is loaded and ready, have you tried the network reset on the bottom of the hub?

What firmware did you update FROM? Was it something in 2.4.0.x, or older maybe? Or were you already running 2.4.1.x?
Most likely the IP changed or some network setting is botched.
If you don't mind resetting the hub network settings, use the network reset button hidden on the bottom. Network Setup | Hubitat Documentation
Then from there you need to verify the correct IP for the hub. There are multiple way for this, the best is probably to look in your router devices list directly, and confirm the IP/MAC.
You can also use findmyhub.hubitat.com to try and find it, a network scanner tool, or even just arp -a from command line.

It was network related. I run a seperate DHCP server and ran into issues with other devices trying to service DHCP requests, seems like a lot of devices have there own DHCP service enabled by default. So I implemented a DHCP guard on my network, so that only one server is allowed to hand out addresses and this seems to be blocking the Hub IP reservation. Guess I will just stick with a static address.
