Could it be you are using the Bridge API with an (outdated) software bridge and not the hardware?
Maintenance endpoints (like /log) never been available for that and new features (like /lock) have not been added after it had been sunsetted.
many thanks for your return.
What do you mean with software/hardware bridge ? I do have a hardware bridge and via the Nuki Android Bridge App I can get the IP, port etc information.
The hardware firmware is up2date for the smart lock, the opener and the bridge.
