Same here on PS4, purchased yesterday, went thru updates and installs, turned on today and still wont connect. Can play solo but yeah no thanks. Network connection on PS4 is normal as usual, this is a CoDBO4 issue. Why has no one answered you????
Ask for a refund now, don't wait. 20 hz servers will not get any better. I was denied because I waited thinking this *****ty company would upgrade their servers.. Not happening
Remove and reinsert disc (if you have one). I did and all of sudden no problem.
