RDK-03013 Error on new TV Box setup

I've been getting error code RDK-03013 on the cable box we recieved today. Repeated the steps provided, tightening the connection and restarting the box, multiple times to the same result.

I would like to direct message a human to help me with this issue, as the AI assistant suggesting to charge and book a professional installation appointment isn't what I want to hear given it couldn't even tell me what in the device was causing the "network interference" in the first place.
