BrewBlox Installation Problem

I’ve now removed both spark services and added one back - same problem. I attach the brewblox and ui log files.brewblox.log (222.2 KB) brewblox-logs.json (1.8 KB)

I’m concerned that the controller’s display has gone blank (although the led still blinks away happily). Also, it used to beep on startup, but it no longer happens. This all occurred after the recent firmware update.
