Since DbD doesn't use dedicated servers, it's an issue with your console connecting to the host.
So it could be your internet connection, PSN playing up (yes, it happens) or something else... like your wifi signal not being strong enough.
First thing I'd try is to wire your PS4 to your router and see if that fixes it. If not, it might just be a PSN blip.
