I keep running into issues with the ZWave to MQTT Web UI becoming unavailable. My browser just sits there indefinitely, before I eventually give up and hit esc or reload to try again. The log output then shows a response with a 499 status code (client closed connection). The logs also show whatever node updates might be happening in the background, so it appears the service in general continues working and it’s just the web that stops. The only resolution I’ve found atm is to reboot the whole ZWave to MQTT integration.
Any suggestions on how to to debug this further? Memory, swap, disk use, etc are all pretty low so it doesn’t appear to be resource contention.
