So I run a lot of Shelly IP, custom https calls to other 3rd party devices and was running with no issues on 188.8.131.52 long term. I upgraded early on with 184.108.40.206 and 122 and had the same crash. So I went back to the old release (wife yelled at me). Now I'm trying to move up to 220.127.116.11 and found this morning the Hubitat is in failure mode.
Something has changed in the way TCP calls are being handled and the capacity breaks down or runs out. I'm going to monitor this now better and I'll get more details. 18.104.22.168 is not stable.
Most of us are running 22.214.171.124 and it's fine for us. That said are you running a static ip or DHCP? Start with pressing the reset button on the bottom of the hub with a toothpick or paper clip (only round hole out of all the square ones) for 7 seconds. This will reset the network settings in case something is wrong. I would also restore the previous days db just to ensure you don't have corruption going on.
