Cabled devices not found - Netgear Device Tracker

Hello

I have moved my docker install from a laptop back onto my QNAP (in a docker) and all is working perfectly. Except the Netgear device tracker. It is adding wifi devices to known_devices.yaml, but nothing I have using CAT5. I did work in the other instance and if I add them manually, they still don’t work.

Most odd as I use this to track if devices are online or offline etc.

Any ideas please?

Cheers
Mark
