This morning I woke up and found my cameras still in night mode and my Inovelli switches still showing the hub was in night mode. I found the hub was saying error 500 when I tried to get to the dashboard or normal web interface. I rebooted from :8081 and after the reboot the hub was in its new hub state with the only options to setup the hub from scratch or restore. I clicked the restore from backup at the bottom and selected yesterday's (8-7 2am) auto backup and after that everything seems to be back to normal.
The hub (C-3) had been on update 184.108.40.206 for about a week when this occurred.
This is the first time this has happened in the two years I've been using my hub, my guess is something went wrong during the backup or DB cleanup process last night since there was no backup for last night and the hub had been working at 11pm when I went to bed.
