Unfortunately, my recovery is not going so well. The soft reset appears to do nothing.
When I open the diags tool it would seem I'm already logged in. I've tried logging out and back in. Logs straight in without asking for MAC. I've tried clearing the browser cache; which didn't work. A reboot just takes me back to the corrupt database page.
I'm in the middle of trying to downgrade to see if earlier versions are any more successful.
Update: downgraded to v2.2.9.146. Login behaviour still the same. I'm definitely not authenticated properly as commands are returning a 401.
What are your issues? - it wasn't clear in your post. Can you get to the UI?
For basic corruption in my experience a soft reset usually works great so if you've done that then there is something else. For Z-Wave table corruption that's a whole different thing - usually requires a reset EXCEPT now with the upgraded firmware this is a lot more manageable.
Have you tried rebooting your switch/router/firewall - maybe it's a network thing? Also temporarily use a different browser like Firefox (or whatever).. that way you know the cache is "clean". (see @thebearmay's more relevant comment below)
This is new. It doesn't seem to like the soft-reset input. I've also tried clicking soft-reset while logged out to see if I get asked for the mac. It never asks.
For your privacy protection, the login is set to time out periodically. If you see Error 401 displayed, please Log Out of the Diagnostic Tool, then close all your browser's windows and log back in using the hub's MAC address. You can find you hub MAC address on the bottom of your hub, or go to Hub Details for information on how to find your hub MAC address from the Hubitat Web Interface.
Firefox is my default browser so initially that.
I've switched to chrome to try have a clean a session as possible
Both have the same behaviour and I have now tried with an incognito window
I just tried a hard reboot inbetween clearing the browser cache and browsing. Same result. I don't get asked for a mac and then see 401 from the soft reset page.
