NAT type is a networking issue that can occur on PlayStation 4. When this issue occurs, your device is unable to communicate with other devices in your network. This can cause problems such as not being able to play games or watch videos. To fix this issue, you will need to change your NAT type. To do this, you will need to find the network adapter that is connected to your PlayStation 4 and open its properties. Under the Network tab, you will need to find the box that says “NAT Type.” Once you have found this box, change it to “None.” This will fix the NAT type issue on your PlayStation 4.
