This sounds a bit related to Ensuring "CoAP Transport" is installed after openHAB upgrade.
I’m now away from home, but I notice my openHAB is now offline, after updating to 4.3.1.
I’m going to do some digging tomorrow, but I assume it keeps restarting openHAB before Coap is installed, failing the if
clause after next restart etc. ad aeternam.
However, I think I changed the echo
commands by mail
commands, so I would expect my mailbox to get flooded… But no mails have arrived.
