Why Are You Getting Error 81110013?
Unlike standard crashes, error 81110013 is strictly a network communication block. Gaijin’s servers are trying to authenticate your profile, but something is severing the connection before the data transfer finishes. Let’s break down the most common culprits:
| Root Cause | What is Happening? | Immediate Solution |
|---|---|---|
| Overzealous Antivirus | Security software is falsely flagging War Thunder’s anti-cheat or network packets. | Whitelist the game folder. |
| Corrupted DNS Cache | Your PC is trying to connect to an outdated or offline server IP address. | Flush DNS via Command Prompt. |
| Server Downtime | Gaijin servers are down for maintenance or experiencing a DDoS attack. | Check server status online. |
| Router/NAT Issues | Your home router is dropping incoming authentication packets. | Reboot the router entirely. |
Step-by-Step Fixes to Resolve the Error
If checking the official Gaijin Support Center confirms the servers are up, follow these essential steps to fix the client-side error on your PC:
1. Flush Your DNS and Reset IP
Clearing your network cache resolves 80% of these connection timeouts.
- Press the Windows Key, type cmd, right-click Command Prompt, and select Run as Administrator.
- Type
ipconfig /flushdnsand hit Enter. - Next, type
netsh winsock resetand hit Enter. - Restart your computer.
2. Add Exceptions to Windows Firewall and Antivirus
Often, a recent game update changes file signatures, causing your antivirus to block the game.
- Open Windows Security → Virus & threat protection.
- Click Manage settings under Virus & threat protection settings.
- Scroll down to Exclusions and click Add or remove exclusions.
- Select Add an exclusion → Folder, and navigate to your War Thunder installation directory (e.g.,
C:\Program Files (x86)\Steam\steamapps\common\War Thunder).
3. Delete the “cache” and “compiledShaders” Folders
Corrupted temporary files can also halt the profile loading phase.
- Navigate to your War Thunder installation folder.
- Locate the folders named cache and compiledShaders.
- Delete both folders completely (the game will automatically recreate clean versions upon the next launch).
- Launch the game through the launcher and wait for it to verify files.
