Are you currently facing the frustrating and persistent Vanguard Error VAN 185? As of December 20, 2025, this error remains one of the most common hurdles for players trying to launch or play Riot Games titles like Valorant and League of Legends, especially after recent system updates or extended client uptime. This connection error essentially signals a critical breakdown in communication between the Riot Client and the powerful Riot Vanguard anti-cheat system, often blocking access to your favorite games and leaving you stuck in a frustrating loop.

The good news is that the solution is rarely a complex hardware issue, but rather a misconfiguration or a simple re-authentication requirement that can be resolved quickly. We have compiled the most recent and fully updated fixes for 2025, moving beyond simple restarts to tackle the root causes, including Windows 11 security conflicts and deep client issues.

Understanding Vanguard Error VAN 185: Causes and Context

To effectively fix the VAN 185 error, you must first understand its origins. Riot Games’ proprietary anti-cheat software, Riot Vanguard, is a kernel-level application designed to maintain competitive integrity in games like Valorant and League of Legends. The VAN 185 error code is one of several connection-based errors, but it carries a few distinct meanings that dictate the appropriate fix.

The primary and most frequent cause of VAN 185 is a Connection Error related to Vanguard re-authentication. Riot has noted that leaving the League Client (or Riot Client) running for longer than seven days can trigger this error, as the anti-cheat system requires a fresh security handshake.

However, there are two other critical, though less common, causes:

  • Vanguard System Conflict: The anti-cheat system is either blocked, missing, or misconfigured on your system, often due to a conflict with other software, a corrupted installation, or a failure to meet Windows 11 security requirements (specifically TPM 2.0 support).
  • Potential Hardware Ban: In rare cases, Riot Games has classified VAN 185 as a Hardware Ban error. If all simple fixes fail, this possibility must be considered, and direct contact with Riot Support is the only recourse.

The error essentially indicates that the Game Client cannot communicate securely with the Riot servers because the Vanguard anti-cheat component is not properly authenticated or running as expected.

The 4-Step Master Fix List for VAN 185 (2025 Edition)

The following list of solutions is organized from the simplest and most common fix to the most complex, ensuring you resolve the VAN 185 error with minimal downtime.

Step 1: The Essential Client and PC Restart (Re-authentication)

Since the most common cause is a re-authentication failure after long uptime, this is always the first step. It forces the Riot Client and Vanguard to re-establish a secure connection.

  1. Close All Riot Processes: Completely exit the Riot Client (and any running game like Valorant) by right-clicking the icon in your system tray and selecting 'Exit' or 'Quit'.
  2. Restart Your PC: Perform a full system restart. Do not just put your computer to sleep.
  3. Relaunch the Game: Open the game (Valorant or League of Legends). This action will automatically launch Riot Vanguard and attempt the necessary re-authentication with the Riot servers.

If the error persists, especially if you see it pop up during Champ Select in League of Legends, proceed to the next step.

Step 2: The Core Fix—Reinstalling Riot Vanguard

A corrupted, misconfigured, or blocked Vanguard installation is the second most likely cause. A clean reinstallation is highly effective and often resolves the conflict instantly.

  1. Uninstall Vanguard: Go to the Windows Control Panel (or Settings -> Apps & Features). Locate Riot Vanguard and select 'Uninstall'. Confirm the uninstallation.
  2. Restart Your PC (Crucial Step): After uninstalling, you must restart your computer for the removal to be complete.
  3. Reinstall Vanguard: Launch either Valorant or League of Legends. The Riot Client will detect that Vanguard is missing and automatically prompt you to download and install the latest version. Allow the process to complete.
  4. Final Restart: After the automatic installation is finished, perform one final PC restart.

This process ensures you have a fresh, clean, and up-to-date version of the anti-cheat software, resolving most system conflicts.

Step 3: Advanced System and Security Checks (Windows 11 and Malware)

In 2025, the relationship between Riot Vanguard and Windows 11 security features, such as TPM 2.0 and Secure Boot, has become a more frequent source of errors. Additionally, malicious software can interfere with Vanguard's operation.

  • Verify Windows 11 Security Requirements: Ensure your Windows 11 system supports and has enabled TPM 2.0 and Secure Boot in your BIOS/UEFI settings. While this is more commonly associated with other Vanguard error codes like VAN 128, an incompatibility can still trigger a connection failure like VAN 185.
  • Run System Scans: Use reputable anti-virus or anti-malware software to perform a full System Scan. Malware or other intrusive programs can cause conflicts that block the Vanguard kernel-level driver from running correctly.
  • Check Firewall and Antivirus Exclusions: Temporarily disable your third-party firewall and antivirus programs to see if they are blocking Vanguard. If the game launches, you must add Riot Client and Vanguard as exceptions to your security software.

Step 4: The Last Resort—Contacting Riot Support

If you have diligently followed the first three steps and the VAN 185 error persists, the issue may be beyond your local machine, or you may be facing the rare Hardware Ban scenario.

  • Submit a Ticket: Visit the official Riot Games support page and submit a detailed ticket. Include the error code (VAN 185), the game you are playing (Valorant or League of Legends), and a list of all the troubleshooting steps you have already performed (Steps 1-3).
  • Provide Logs: Riot Support staff are likely to ask for game and system logs. Be prepared to provide these to expedite the resolution process, especially if the issue is a complex communication problem with the Riot servers.
