By following these instructions in order, you increase the chances of fixing the error quickly. Let’s get started and fix Error Code 601 so your game runs without problems.

Remember, patience is key. Sometimes small adjustments can make a big difference in connectivity issues.

Quick Note: Prerequisites and Initial Checks

  • Check Your Internet Connection: Ensure your PC is connected to a stable internet network. A weak or dropping connection can cause connection errors.
  • Verify Square Enix Server Status: Sometimes, the problem is on Square Enix’s end. Visit their official server status page or social media to confirm if their servers are operational.
  • Restart Your PC and Router: Simple restarts can refresh your system and network settings, often resolving temporary glitches.
  • Update Windows 11: Keep your operating system updated to avoid compatibility issues with games or network services.

Step 1: Run the Game as Administrator

Running the game with administrator privileges allows it to access necessary system resources and network permissions that might otherwise be blocked.

  1. Right-click the game’s shortcut or executable file.
  2. Select Properties from the context menu.
  3. Go to the Compatibility tab.
  4. Check the box labeled Run this program as an administrator.
  5. Click Apply and then OK.
  6. Launch the game and see if the error persists.

This step ensures the game has elevated permissions to communicate properly with the Square Enix servers.

Step 2: Temporarily Disable Firewall and Antivirus Software

Windows Firewall or third-party antivirus programs might block the game’s connection to the internet, causing Error Code 601.

  1. Open Windows Security by searching for it in the Start menu.
  2. Click on Firewall & network protection.
  3. Select your active network (usually “Private network”).
  4. Toggle off the Microsoft Defender Firewall.
  5. Try launching the game again.

If the game works, your firewall was likely blocking it. Instead of leaving the firewall off, add the game as an exception:

  1. Go back to Firewall & network protection.
  2. Click Allow an app through firewall.
  3. Click Change settings, then Allow another app.
  4. Browse for the game executable and add it.
  5. Enable firewall again and test the game.

Similarly, disable your antivirus temporarily and check the game. If disabling fixes the error, add the game to the antivirus exclusion list.

Step 3: Reset Network Settings

Resetting your network settings can solve underlying connectivity issues that cause Error Code 601.

  1. Press Win + I to open Settings.
  2. Navigate to Network & internet.
  3. Scroll down and click on Advanced network settings.
  4. Under More settings, select Network reset.
  5. Click Reset now and confirm.
  6. Your PC will restart automatically.
  7. After restart, reconnect to your network and try the game again.

This process reinstalls all network adapters and restores network components to their default settings, eliminating misconfigurations.

Step 4: Flush DNS and Renew IP Address

Sometimes, corrupted DNS cache or IP conflicts cause connection errors. Flushing DNS and renewing your IP address can fix these.

  1. Press Win + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. In the command window, type the following commands one by one, pressing Enter after each:
ipconfig /flushdns
ipconfig /release
ipconfig /renew

After completing these commands, close the Command Prompt and relaunch the game.

Step 5: Update Network Drivers

Outdated or faulty network drivers can cause connectivity problems with online games.

  1. Right-click the Start button and select Device Manager.
  2. Expand the Network adapters section.
  3. Right-click your network adapter and select Update driver.
  4. Choose Search automatically for drivers.
  5. If an update is found, follow the on-screen instructions to install it.
  6. Restart your PC and try launching the game again.

Updating drivers ensures compatibility and can resolve bugs affecting network connectivity.

Alternative Method: Use a VPN

If your ISP or region has restrictions affecting Square Enix servers, using a VPN might help bypass these blocks. However, use reputable VPN services to avoid latency or other issues.

Try connecting to a server near your actual location and then launch the game. If the error disappears, your regular network path may be the cause.
