Quick Note Before You Start

  • Check your internet connection: A stable and fast internet connection is crucial for PS4 network functions.
  • Ensure your PS4 and Windows 11 PC are updated: Both devices should have the latest system updates applied.
  • Confirm your PS4 and PC are on the same local network: This is important if you are using Remote Play or similar services.
  • Restart your devices: Sometimes, a simple restart can fix temporary glitches causing these errors.

Step-by-Step Troubleshooting Guide

Step 1: Restart Your PS4 and Windows 11 PC

Begin with restarting both your PS4 console and your Windows 11 computer. This simple action can clear temporary system glitches or network conflicts that might cause errors 34878-0 and 30005-8.

Why this helps: Restarting refreshes the system memory and network connections, often resolving minor bugs.

Step 2: Check and Reset Your Network Connection

Unstable or slow networks are a common cause of connection errors. Follow these steps:

  1. Disconnect your PS4 and PC from the internet.
  2. Restart your router/modem by unplugging it for 30 seconds, then plugging it back in.
  3. Reconnect both devices to your Wi-Fi or wired network.
  4. Test your internet speed using an online tool to ensure it is sufficient for gaming.

Why this matters: A fresh connection often eliminates network issues that prevent your devices from communicating properly.

Step 3: Update Your PS4 System Software

Outdated software can cause compatibility issues. To update your PS4:

  1. Go to Settings on your PS4.
  2. Select System Software Update.
  3. If an update is available, follow the prompts to download and install it.

Why update? Updates fix bugs, improve security, and enhance connectivity, reducing error chances.

Step 4: Update Windows 11 and Remote Play App

Make sure your Windows 11 system and PS Remote Play app (if used) are up to date:

  1. Open Settings > Windows Update and install any available updates.
  2. Open Microsoft Store, search for PS Remote Play, and update it if needed.

Why do this? Compatibility between your PC and PS4 depends on both being current.

Step 5: Clear Cache on Your PS4

Corrupted cache files may cause errors. To clear cache:

  1. Turn off your PS4 completely (not Rest Mode).
  2. Unplug the power cable from the back of the console.
  3. Wait at least 30 seconds.
  4. Plug the power cable back in and turn on your PS4.

Why this helps: Clearing cache can resolve issues caused by corrupted temporary files.

Step 6: Adjust Your Network Settings (Port Forwarding)

If errors continue, your router might be blocking necessary ports. Port forwarding opens these for smoother PS4 connectivity:

  1. Access your router’s admin panel (usually by entering 192.168.1.1 or 192.168.0.1 in your browser).
  2. Log in with your router credentials.
  3. Locate the Port Forwarding section.
  4. Forward the following ports for PS4:
    • TCP: 80, 443, 3478, 3479, 3480
    • UDP: 3478, 3479
  5. Save changes and restart your router.

Why this is necessary: Opening these ports allows your PS4 to communicate freely with PlayStation Network servers.

Step 7: Reinstall PS Remote Play (If Applicable)

If you use Remote Play and errors occur, reinstalling the app can fix corrupted files:

  1. Open Settings > Apps on Windows 11.
  2. Find PS Remote Play and select Uninstall.
  3. Go to Microsoft Store, search for PS Remote Play, and reinstall it.

Why reinstall? Fresh installation removes bugs that may cause connection failures.

Alternative Methods and Advanced Options

Use a Wired Ethernet Connection

For more stable connections, connect both your PS4 and PC directly to your router using Ethernet cables. Wired connections reduce interruptions caused by Wi-Fi interference.

Change DNS Settings on PS4

Sometimes, changing DNS servers can improve connectivity:

  1. Go to Settings > Network > Set Up Internet Connection.
  2. Select your connection type (Wi-Fi or LAN).
  3. Choose Custom setup.
  4. Set IP Address Settings to Automatic.
  5. Set DHCP Host Name to Do Not Specify.
  6. For DNS Settings, choose Manual.
  7. Enter preferred DNS: 8.8.8.8 (Google DNS) and alternate DNS: 8.8.4.4.
  8. Complete the setup and test your connection.

Why change DNS? Some DNS servers are faster or more reliable than your ISP’s default, improving connectivity.
