- We recommend a wired Internet connection to your PS4.
- If you are using a Wi-Fi (wireless) connection, move your PS4 system closer to the access point or router. Make sure there are no obstructions between them.
- Other devices on your network might be using a large amount of bandwidth. Wait until they are idle before using Remote Play.
- Confirm that all of the ports >UDP 9296, UDP 9297, UDP 9303 are open. If that port cannot be used, you should adjust your router's port forwarding setting to allow communication to the PlayStation 4 from the Internet. For details on the port numbers used for remote play and how to adjust settings, you should refer to the instructions supplied with your router or contact your ISP.
- If the PS4 is connected to the Internet via two or more routers, communication may not work correctly.
The anti-virus software on your computer may be blocking the PS4 system's communication with your computer. Try disabling the firewall settings on your antivirus software, or adding Remote Play application to the firewall program exceptions. For details, refer to the instructions provided by the antivirus software.
