Doorbell Elite - Ethernet Connection Failing on Setup

I have a Ring Elite that will not connect to the internet through Ethernet during setup. To confirm: - I have reset the doorbell several times using the black button on the front. I have also reset the router, switch, and modem. There are no other internet issues in the house. - There is no issue connecting to Wifi during setup (which is connected to the same ethernet switch as the Ring Doorbell) - The POE device is powering the doorbell without any issue - The house hiring is Cat6 cable installed two years ago I'd really appreciate any ideas or help on how to resolve this. Thanks!
