I just tried upgrading from 5.8.3 to 5.8.4 and all seemed to go well with getting 4 finalization beeps. I cleared Java and downloaded new launcher. I went to connect to admin console and was indicating still on 5.8.3 so I initiated a reboot and have now lost connectivity. I never got the 4 beeps and when opening the launcher, my local address is no longer showing and only the "polisy.local" address shows up with a UUID of all "0" except for the final digit which is "1" but is showing it is on 5.8.4. I have tried power cycling the Polisy and the same issue occurs. When I try going to the portal address in the launcher and log in, all devices are showing no status or functionality. My whole system is now down and I have submitted a ticket so am just awaiting a response.
