Mini cable box stopped working when I removed X1 dvr from basement tv

Hoping to get some help , I have 2 boxes on 2 TVs and have been getting the basement TV set up on x stream though my Fire stock , that part went great.

so the trouble started when I disconnected the X1 dvr box from that same basement tv ( since I no longer need it ) . Set up to return equipment on the xfinity site . Then when the wife goes to watch the upstairs tv which does use a mini xfinyty cable box no good won’t connect.

trying to figure if it’s a wiring issue or a setting( primary box) , or maybe I have to keep the DVR and return the mini box ? Any help would be appreciated
