While many waited it out, some found temporary workarounds. Let’s go over all the proven solutions.

FIXES FOR PC (Steam/Game Pass)

1. Delete LauncherInfo.hllinfo

A corrupted config file can prevent proper server communication.

• Go to your Steam Library → Right-click Hell Let Loose → Properties → Installed Files → Browse
• Delete LauncherInfo.hllinfo (don’t worry, the game will create a new one automatically)

2. Run Steam & Game as Administrator

This ensures proper permissions for network access.

For Steam:

• Navigate to: C:\Program Files (x86)\Steam
• Right-click steam.exe → Properties → Compatibility → Check Run this program as an administrator

For the Game:

• Go to game’s install folder → Right-click HLL.exe → Properties → Compatibility → Enable admin mode

3. Add to Windows Defender Exclusions

Whitelist these files:

• HLL.exe, HLL-Win64-Shipping.exe, EasyAntiCheat.exe, and Launch_HLL.exe
• Path: Steam\steamapps\common\Hell Let Loose

How-To:
Windows Settings → Privacy & Security → Windows Security → Virus & Threat Protection → Manage Settings → Add Exclusions

4. Flush DNS & Reset Network Stack

Use Command Prompt (Admin):

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

Then restart your PC.

5. Switch to Cloudflare DNS

• Control Panel → Network and Internet → Network Connections
• Right-click active connection → Properties → Select IPv4 → Use the following DNS:
  • Preferred: 1.1.1.1
  • Alternate: 1.0.0.1

This can reduce latency and avoid ISP misrouting.

FIXES FOR XBOX USERS

1. Clear Alternate MAC Address

• Settings → General → Network Settings → Advanced Settings → Alternate MAC Address → Clear
• Restart console

2. Reset Console (Keep Games & Apps)

• Settings → System → Console Info → Reset & Keep My Games & Apps

Warning: You’ll need to log back into all accounts.

3. Reauthorize App Permissions

• Visit Microsoft Privacy Dashboard
• Revoke Hell Let Loose access → Restart game to request new permissions

4. Wait for Certificate Sync (If Update Ongoing)

If Microsoft just updated backend certificates, you may need to wait 30–60 minutes before new credentials sync with your console/game.

Quick Check with Mobile Hotspot

Try tethering your PC/Xbox to a mobile hotspot:

• If the game works, the problem is your router/ISP
• If it doesn’t, the issue is your system or game installation

Pro Tips to Prevent This Error in Future

• Avoid special characters in your Steam or Xbox username (they may break network parsing)
• Always exit the game properly before shutting down
• Don’t interrupt updates or crash the launcher during patching
• Keep Windows/Xbox system software up to date
