Just my guest but can you check if they MAC address is different? I once deploy a few pi based on the same backup image, forgot to run the factory-reset that cause multi device with the same MAC in the local network.

Thank for reply. I read that and installed the update on one of the development Pi. But I wonder why only 1 of the 5 RevPis has the problem while they are running the same software. The in production RevPis are installed in factory without the internet access(we are not allowed to), so it will take ...

Hello. We have 5 RevPi core 3, all running the same software(deploy from the same .img file then run the factory-reset script) and connected to a DIO module. 2 of them are in testing environment, 3 are in production.
