Test your connection to the Internet
Start by testing your network connection with the following steps:
Start at the PlayStation 4's Dynamic menu.
Press up to go to the Function bar (at the top of your screen).
Scroll to Network and press X.
Select Test Internet Connection.
Performing the Network connection test on PS4
If the test shows your connection as NAT Type 3, communication with other PS4 systems might be impossible, or you may encounter problems connecting to the network.
Please follow the steps below to improve your Multiplayer experience:
Restart Your Network Hardware
Turn off your PlayStation 4 and your Modem/Router and wait for 15 - 30 seconds.
Fully power up your Modem/Router (it may take a couple of minutes to re-establish your connection).
Turn on your PlayStation 4 and test the connection again by following the steps at the beginning of the article.
At this point if you still have trouble then you may have a firewall interfering with your connection. Please configure the following network ports within your router from your PC:
Ports used by The Division:
TCP 80, 443, 27015, 51000, 55000 to 55999, 56000 to 56999
UDP: 33000 to 33499
Ports used by PSN:
TCP: 80, 443, 3478, 3479, 3480
UDP: 3478, 3479
Directions for configuring network ports are specific to the software and hardware being used, and can be found by visiting the manufacturer's website.

If this does not solve your issue, try placing your PlayStation 4 in the DMZ of the router or establishing a direct connection to your modem (where available) and retry.
4. Traffic Throttling / Blocked Ports
There may also be certain restrictions set by your Internet Service Provider (ISP). If you continue to have trouble, please contact your ISP for details on any specific restrictions on the previously mentioned network ports.
