Adding receiver gets error message - DirecTV

#1
I have (3) receivers. Wireless. The U-Verse App shows (2) receivers. When I try and add the other receiver I receive an error message '... cannot communicate with server...error 3000'
CS has no clue as to why. It's absolutely a please to speak with a tech that has a reply. 'I don't know' and that's it.
