You may be able to connect by improving your network. Try these Network Connection troubleshooting tips:
- Make sure your PlayStation 4 and your computer are both connected to the same stable, high-speed network with upload and download speeds of at least 5 Mbps.
- We recommend a wired Internet connection for your PlayStation 4.
- If you are using a Wi-Fi (wireless) connection, move your PlayStation 4 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, 9297, 9303 are open. If not, adjust your router's port forwarding settings to allow communication between the PlayStation 4 and the Internet. For instructions on how to adjust these settings, please refer to the manual supplied with your router or contact your ISP.
- The anti-virus software on your computer may be blocking communication between your PlayStation 4 and the computer. Try disabling the firewall settings on your anti-virus software, or adding the Remote Play application to the firewall program exceptions. For details, refer to the instructions provided by the anti-virus software publisher.
For more details about your network, please contact your ISP.
