Hue binding lost pairing after service restart

Hi I’ve got the same issue since some day. But i don’t know what i changed. Sure I did upgrade the Hue Firmware but no changes in Openhab. After every Restart of the Raspberry Pi I have to Press the Button on the Hue to connect it again.

I would be very interested in any hint.

ok. I’ve found this thread that explains the error.

Seems to be only an error in the Log. Hue Binding works after reboot. Just brings up the messages to bind again.
