Fix Valorant Error VAN 1067 – Vanguard Connection Issue

Symptoms

When launching Valorant, players encounter a pop-up error with code VAN 1067. The game may close immediately or fail to start. Vanguard may show as not running in the system tray. The error message typically reads: "Vanguard has encountered a problem. Please restart your PC and try again." Sometimes the game will appear to launch but then crash back to desktop.

Root Causes

VAN 1067 is a connection error between the Vanguard anti-cheat service and Riot's authentication servers. Common causes include:

• Vanguard service not running – The vgc service is stopped or disabled.
• Firewall or antivirus blocking – Security software may block Vanguard's network access.
• Corrupted Vanguard installation – Missing or damaged files prevent proper startup.
• Network issues – DNS problems, proxy/VPN interference, or unstable internet.
• Windows services conflict – Other services (e.g., secondary logon) interfere.
• Outdated Vanguard – An older version may not connect to current servers.

Step-by-Step Fix

1. Restart Vanguard Service

1. Press Win + R, type services.msc, press Enter.
2. Find vgc (Vanguard service).
3. Right-click and select Restart. If it's not running, choose Start.
4. Set startup type to Automatic (right-click > Properties).
5. Launch Valorant again.

2. Run Services as Administrator

1. Open Command Prompt as administrator (Win + X > Terminal Admin).
2. Type: net start vgc and press Enter.
3. If it fails, run: sc config vgc start= auto then net start vgc.
4. Close and test Valorant.

3. Check Firewall and Antivirus

• Add exceptions for VALORANT.exe and Vanguard.exe in Windows Defender Firewall.
• Temporarily disable third-party antivirus (re-enable after test).
• If using VPN or proxy, disconnect and try again.

4. Repair Vanguard Installation

1. Close Valorant completely.
2. Open Add or Remove Programs.
3. Find Riot Vanguard, click Uninstall.
4. Restart your PC.
5. Launch Valorant – it will reinstall Vanguard automatically.

5. Network Troubleshooting

• Flush DNS: Open CMD as admin, type ipconfig /flushdns.
• Reset Winsock: netsh winsock reset then restart PC.
• Change DNS to Google (8.8.8.8 / 8.8.4.4) in network adapter settings.

6. Check Windows Updates

Ensure Windows is fully updated. Go to Settings > Update & Security > Check for updates. Install all pending updates and restart.

Alternative Fixes

• Clean boot – Disable non-Microsoft services via msconfig to isolate conflicts.
• Reinstall Valorant – If all else fails, uninstall both Valorant and Vanguard, then reinstall from official site.
• Run as administrator – Right-click Valorant shortcut > Properties > Compatibility > Run this program as administrator.
• Disable IPv6 – In network adapter properties, uncheck Internet Protocol Version 6 (TCP/IPv6).

Prevention

• Keep Vanguard and Valorant updated automatically.
• Do not disable Vanguard service – it must run at startup.
• Add Valorant and Vanguard to your antivirus whitelist.
• Avoid using VPNs or proxies while playing.
