problem communicating with device (did work, now it doesn't)

[Skankrabbit]

this is your esphome problem, you can delete your esphome addon, re isntall it.

ok, so I can see/flash the board via usb when its plugged into my raspberry pi (Homeassistant server), I can also see the device can connect via wifi on my network by logging into the modem, so wifi and usb connections seem fine. I cannot get it to connect with ethernet connection though no matter what I do. Ive deleted the yaml file and started from scratch numerous times, then tried to setup with the ethernet cable, tried several cables, and followed the ethernet tutorial but its completely dead. No lights on the ethernet port on KC868 and no lights on my ethernet switch port when its connected.  Any suggestions, or is the ethernet port cooked..??
