The Ubiquitous Windows 11 VAN 1067 Disconnect

One of the most frustrating errors in Valorant is VAN 1067, which forcefully crashes the game client back to the desktop shortly after launching. On Windows 11, Riot Vanguard strictly enforces hardware security attestation, and any misconfiguration in your motherboard BIOS will trigger this disconnect.

The Top 3 Root Causes of VAN 1067

  • Legacy CSM (Compatibility Support Module) Enabled: If your motherboard boots in legacy BIOS/MBR mode rather than native UEFI/GPT, Secure Boot cannot be cryptographically verified.
  • TPM 2.0 Disabled or Outdated Firmware: AMD fTPM or Intel PTT must be enabled in BIOS and running firmware version 2.0 or higher.
  • VGC Service Startup Failure: The Windows service vgc responsible for Vanguard communication was stopped or delayed by third-party antivirus software.

Step-by-Step Resolution Protocol

  1. Press Win + R → Type msinfo32 → Verify that BIOS Mode is set to UEFI and Secure Boot State is On.
  2. Press Win + R → Type services.msc → Find vgc → Set Startup Type to Automatic → Start the service.
  3. If using Windows 11 Pro/Enterprise, disable Credential Guard conflicts in Group Policy Editor under System → Device Guard.
