Nest does not work after reboot

Hello,

I wonder, if somebody could help me…
For my new two Nest Protect I installed the Nest Binding v.1.10.0.201705080110. Everything is OK until… I reboot the system; then I am not able to receive the data due to the ‘authorization code not found’ found in the console (see bellow). However, when I change the Pin code in the Nest Developers and change this in the UI then the Nest binding is able to receive the data.
I use OpenHab 2 Build 910.

Thank you very much in advance:
