Arduino to ignition loosing connection


I have an Arduino UNO with an ethernet shield communicating with ignition. I had it working, but when I tried to reconnect the very next day, the status of the device goes from connected to disconnected, and I cannot seem to find what is going on. I have tried rebooting PC, Arduino, different Arduino boards, connected the Arduino as a new device.

any help would be much appreciated.

Thank you

Anything in the logs? Can you communicate with the Arduino over ethernet with anything else?
