Fix: “Communication Error S9052-TAD-W79J” in Monster Hunter Wilds

The error “Communication Error S9052-TAD-W79J” in Monster Hunter Wilds typically occurs due to network-related issues that prevent the game from maintaining a stable connection to its online servers. This can often result from conflicts with network protocols or restrictive firewall settings that block the game’s access to online services.

While a misconfigured internet connection is the most common cause, other factors—such as aggressive antivirus software, VPN interference, or NAT type restrictions—can also contribute to this error.

Before diving into advanced solutions, the first thing you should do is power cycle your router. This step helps refresh the network connection by clearing temporary data, renewing your IP address, and resolving minor connection glitches that may be causing the Communication Error S9052-TAD-W79J.

To do this, unplug your router from the power source, wait for about 30 seconds, then plug it back in. Once the connection is restored, launch the game and check if the error still appears. If it persists, you can follow the detailed methods below.

1. Turn Off IPv6

Many online games like Monster Hunter Wilds primarily rely on IPv4 connectivity, as most game servers and networking infrastructure haven’t fully adopted IPv6 support yet. When your system attempts to use IPv6 connections instead of IPv4, it can lead to several networking issues:

• NAT traversal failures (preventing proper peer-to-peer connections)
• Routing conflicts (incorrect network path selection)
• Firewall restrictions (unexpected port blocking)

These IPv6-related issues often manifest as error codes like Communication Error S9052-TAD-W79J. While IPv6 is the newer protocol, gaming networks still predominantly use IPv4 for compatibility reasons.

If you’re experiencing connectivity problems, you may want to temporarily disable IPv6 to force your system to use IPv4 for game connections. This often resolves these types of networking errors.

1. Click the Start icon, type Control Panel, and press Enter.
   
2. In the Control Panel, select Network and Internet > Network and Sharing Center.
3. From the top left, click Change adapter settings.
   
4. Right-click your active network connection and select Properties.
   
5. Uncheck the box for “Internet Protocol Version 6 (TCP/IPv6)“.
6. Click OK and restart your computer.
   

2. Reset Windows Firewall Settings & Add Game to Whitelist

Firewall settings can sometimes get altered by third-party software, manual changes, or occasional system updates. If Monster Hunter Wilds is being blocked by the firewall—intentionally or by mistake—it may not be able to connect to the game servers. Resetting the firewall restores its default state, removes any custom rules, and allows Windows to reconfigure fresh permissions when the game is launched again.

1. Click the Search icon (magnifying glass) in your taskbar, type “Control Panel“, and press Enter.
2. Select System and Security > Windows Defender Firewall.
3. Click Restore defaults in the left menu and confirm when prompted.
4. Restart your computer and check if the issue is resolved.

If the issue persists, try these additional firewall steps:

1. In Windows Defender Firewall, click Allow an app or feature through Windows Defender Firewall from the left menu.
2. Click Change settings and find Monster Hunter Wilds in the list.
3. Check both Private and Public network boxes for the game.
4. If the game isn’t listed, click Allow another app, browse to the game’s .exe file (usually in your Steam or game installation folder), and add it.
5. Check both Private and Public boxes for the newly added game.
6. Click OK to save changes and restart your computer.

4. Reset the Network Settings

If the issue persists after trying the previous solutions, it’s possible that your current network configuration is misconfigured or corrupted. In this case, performing a full network reset can help. This will restore all network settings to their default state, removing any conflicting changes or custom configurations that might be blocking the game’s connection.

1. Press Windows + I to open Windows Settings.
2. Select Network & Internet from the left panel, then click Advanced network settings at the bottom.
3. Scroll down and click Network reset (this will reinstall network adapters and reset components to default settings).
4. Click the blue Reset now button and confirm when prompted (your internet will temporarily disconnect during this process).
5. Wait for your PC to automatically restart. After rebooting:
   • Reconnect to your Wi-Fi or Ethernet network
   • Test if your original issue is resolved

If the issue still isn’t resolved, reinstalling the game is the final option worth trying. A fresh installation can eliminate any corrupted game files that might be causing the error. However, if the problem continues even after reinstalling, try connecting to the game using a VPN or a different network—such as mobile data through a hotspot. Once you’re successfully connected, you can switch back to your main network. This method has worked for some users and may help bypass the issue.
