H guys,
my KNX binding was running very stable for almost two years. Since yesterday I’m receiving lost connections, and I have to disable/enable the gateway or restart the complete openhab service.
I don’t now what is the reason for that. I didn’t update the openhab version.
See the settings here:
It is a MDT IP Router, Secure is switched off. There should be enough open connections
This is coming from the logs:
