Stuck in red-green-red for days

I’ve had an iotawatt running mostly without issue for a few years now, feeding to Home Assistant. It seems to have gone mostly offline 48 hours ago. Its pingable, but the web interface is not loading, and Home Assistant history shows about 10 data points for each Mains over that 48 hour period. red-green-red lights, sounds like it is recalculating a bad log which should take a few hours? why has it been down for days? Anything i can do to fix it manually? A power cycle obviously didn’t help (tried that before reading up on what the blink code means).

I kinda rely on this thing for charging my car correctly off solar.
