Nuki devices (locks) suddenly offline since 2/4/2024

Hello,
I finally found the solution.
First I deleted the Nuki app and I removed the bridge (no power). Then I installed the Nuki app again and created the 2 smart lock devices. Both of them were off line.
Next I activated the bridge again, and bingo, both devices came online.
Don’t ask me why, but for the moment the problem is solved.

Thanks for your help
Jos
