C41W connection to bridge issue - DirecTV

I was attempting to connect the last C41W to the video bridge yesterday and could not get it to mate. I had no issue with first two. I even moved the third to the location of the first that was successful and no luck. I had CS swap it out and still could not connect to bridge. The customer had to eventually leave and stated they would call back in to add the third later. Does anyone out there have some insight as to why that happened. I've installed several of these with no issues until this one.
