Fix Hell Let Loose Network Error on PC (Steam & Game Pass)

Fix 1: Delete LauncherInfo.hllinfo (Most Effective PC Fix)

A corrupted launcher configuration file can prevent the game from authenticating properly.

Steps

• Open Steam Library
• Right-click Hell Let Loose → Properties
• Go to Installed Files → Browse
• Delete the file:

LauncherInfo.hllinfo

• Relaunch the game (the file is recreated automatically)

Fix 2: Run Steam and Hell Let Loose as Administrator

Running the game with admin privileges ensures network access is not restricted.

Steps

• Close Steam completely
• Navigate to:

C:\Program Files (x86)\Steam

• Right-click steam.exe → Properties → Compatibility
• Enable Run this program as an administrator
• Apply and launch Steam again

Repeat the same steps for HLL.exe inside the game folder.

Fix 3: Allow Hell Let Loose Through Windows Defender

Security software can silently block game network traffic.

Add these files to exclusions

• HLL.exe
• HLL-Win64-Shipping.exe
• EasyAntiCheat.exe
• Launch_HLL.exe

Path

Steam\steamapps\common\Hell Let Loose

Fix 4: Flush DNS and Reset Network Stack

Network cache issues often cause unexplained connection errors.

Steps

• Open Command Prompt (Admin)
• Run these commands one by one:

ipconfig /flushdns
netsh winsock reset
ipconfig /release
ipconfig /renew

• Restart your PC

Fix 5: Switch to Cloudflare DNS

ISP DNS servers may misroute game traffic.

Use these DNS values

• Preferred DNS: 1.1.1.1
• Alternate DNS: 1.0.0.1

Apply this under IPv4 settings of your active network connection.

Steps

1. Go to Settings → General → Network Settings
2. Open Advanced Settings
3. Select Alternate MAC Address
4. Choose Clear and restart the console

Fix 2: Reset Console (Keep Games & Apps)

This refreshes system data without deleting installed games.

Steps

1. Go to Settings → System → Console Info
2. Select Reset console
3. Choose Reset and keep my games & apps

You’ll need to sign back into your account afterward.

Fix 3: Wait for Certificate Sync (If Update Just Released)

After backend or security updates, Xbox services may take time to resync authentication certificates.

If this is the cause, the error usually resolves itself within 30 to 60 minutes.

Fix Hell Let Loose Network Error on PS5

• Restart the console
• Restart your router
• Use wired internet instead of Wi-Fi
• Test with a mobile hotspot to rule out ISP issues
• Ensure system software is fully updated

If the error persists, it is likely server-side.

Test Using a Mobile Hotspot (Important Diagnosis Step)

Connect your PC, Xbox, or PS5 to a mobile hotspot and launch the game.

• If the game works: Your ISP or router is the problem
• If the game still fails: The issue is local or server-side

This step helps avoid unnecessary troubleshooting.
