This is indicative of a connectivity issue. It could be as simple as a corrupted cache on your console or in your network. To check for that, power down your PS4, router, and Internet modem/gateway. Then unplug all three devices from power and leave them disconnected from power for at least 5 minutes. After 5 minutes, re-connect your network devices and once your network is back up, re-apply power to your console and try the game again.
