The First Descendant, a thrilling looter shooter from Nexon, has captivated millions with its engaging gameplay and stunning visuals. However, many players encounter frustrating Game Login Failed errors, such as LE:13 or L:10011, preventing access to servers. These issues often stem from server overloads, network glitches, software conflicts, or anti-cheat problems. This guide provides a step-by-step approach to diagnose and resolve these errors, ensuring you return to farming Descendants and ultimate weapons without delay.

Understanding Common Login Errors in The First Descendant

Login failures in The First Descendant typically display codes like LE:13 (server connection issues) or L:10011 (anti-cheat or kernel conflicts). LE:13 often indicates temporary server downtime, especially during peak hours or after updates, while L:10011 points to local interferences like antivirus blocking Easy Anti-Cheat (EAC).

Other variants include generic ‘Login Failed’ messages due to unstable internet or corrupted files. Recognizing the error code is crucial for targeted fixes. Players on Steam report these peaking post-launch, affecting global queues.

Step 1: Verify Server Status Before Troubleshooting

Before tweaking settings, confirm if the issue is on your end or Nexon’s. Overloaded servers cause widespread LE:13 errors, requiring only patience.

If servers are down, wait 1-2 hours and retry. This resolves 40-50% of login issues without further action.

Step 2: Basic Restart and Connection Checks

Simple reboots fix transient glitches. Start here for quick wins.

  1. Restart the game and launcher: Close The First Descendant via Task Manager (Ctrl+Shift+Esc), exit Steam, then relaunch.
  2. Reboot your PC: This clears EAC conflicts causing L:10011.
  3. Test internet stability: Run a speed test (e.g., speedtest.net). Aim for <50ms ping to game servers. Switch from WiFi to Ethernet for reliability.

Restarting Steam often syncs the latest game version, bypassing version mismatch errors.

Step 3: Optimize Network Settings

Network misconfigurations amplify login failures. Adjust DNS and firewall for smoother connections.

Change DNS Servers

Default ISP DNS can be unreliable. Switch to public options:

  1. Right-click network icon > Open Network & Internet settings.
  2. Change adapter options > Right-click your connection > Properties.
  3. Select IPv4 > Properties > Use the following DNS: Preferred 8.8.8.8, Alternate 8.8.4.4 (Google) or 1.1.1.1/1.0.0.1 (Cloudflare).
  4. Save and flush DNS: Open CMD as admin, type ipconfig /flushdns.

This resolves routing issues to Nexon servers.

Configure Windows Firewall

Firewalls block game traffic. Whitelist The First Descendant:

  1. Search ‘Windows Defender Firewall’ > Allow an app through firewall.
  2. Click ‘Allow another app’ > Browse to Steamapps\common\The First Descendant\FirstDescendant.exe.
  3. Add and check Private/Public boxes.

Step 4: Verify Game Files and Update System

Corrupted files cause persistent logins fails. Use Steam’s tools:

  1. In Steam Library, right-click The First Descendant > Properties > Installed Files > Verify integrity of game files.
  2. Check Windows Updates: Settings > Update & Security > Check for updates.

This replaces damaged EAC or NGService files. For NGService errors, delete from install folder and verify.

Step 5: Handle Antivirus and Anti-Cheat Conflicts

Third-party antivirus clashes with EAC, triggering L:10011.

  • Temporarily disable: Pause real-time protection in Avast/Norton/etc. Test login.
  • Add exclusions: Exclude game folder and Steam in antivirus settings.
  • Reinstall EAC: If persistent, delete NGService file and let Steam redownload.

Windows Defender users: Add folder exclusion via Virus & threat protection.

Advanced Fixes for Stubborn Errors

If basics fail:

  • Flush network stack: CMD as admin: netsh winsock reset, netsh int ip reset, reboot.
  • Run as admin: Right-click Steam/launcher > Run as administrator.
  • Clean boot: Disable non-Microsoft services via msconfig to isolate conflicts.
  • VPN test: Use a gaming VPN briefly to bypass ISP throttling (disable after).

Platform-Specific Tips

Steam (Primary Platform): Always verify files post-update. Group discussions highlight LE:13 fixes via restarts.

Console: Clear cache (PS5: Rebuild database; Xbox: Power cycle). Check NAT type.

Preventing Future Login Issues

Proactive steps minimize recurrences:

  • Enable auto-updates in Steam.
  • Use wired connection.
  • Whitelist game preemptively.
  • Monitor server status during events.
