Is the infamous Vanguard error VAN 81 keeping you from diving into the Summoner's Rift? Don't worry, you're not alone! This is a common issue that many League of Legends players face, and it's almost always related to Riot's anti-cheat software, Vanguard. But fear not, because we're here to guide you through a comprehensive, step-by-step process to get you back in the game.
Ready to fix this pesky error and get back to your climb? Let's get started!
Step 1: The First Line of Defense - Restart Everything!
Before we dive into more technical solutions, let's try the simplest and often most effective fix. This error can often be triggered by the Riot Client or Vanguard being active for too long, or by a temporary glitch.
First, completely close League of Legends and the Riot Client. Don't just minimize them; make sure they are fully shut down.
Open your Task Manager (you can do this by pressing
Ctrl + Shift + Esc).In the "Processes" tab, look for any processes related to Riot Games, League of Legends, or Vanguard. This might include:
RiotClientServices.exe
LeagueClient.exe
RiotClient.exe
RiotVanguard.exe
Right-click on each of these processes and select "End task." This ensures they are completely closed.
Now, restart your computer. This is a crucial step as it refreshes all system processes and can resolve temporary conflicts.
After your PC has rebooted, launch the Riot Client and then League of Legends. Check if the error is gone. If so, great! If not, move on to the next step.
Step 2: Checking and Configuring the Vanguard Service
Vanguard's anti-cheat system relies on a service running in the background called "vgc". If this service isn't running or isn't configured correctly, you'll likely face the VAN 81 error.
Sub-heading: Verifying the 'vgc' Service Status
Press the
Windows key + Rto open the Run dialog box.Type
services.mscin the box and press Enter. This will open the Windows Services window.In the list of services, find the one named vgc.
Check the "Status" column. It should say "Running". If it doesn't, this is a likely culprit.
Also, check the "Startup Type" column. It should be set to "Automatic" or "Automatic (Delayed Start)". If it's set to "Manual" or "Disabled", that's a problem.
Sub-heading: Configuring the 'vgc' Service to Start Automatically
If the service isn't running or isn't set to start automatically, follow these steps:
Right-click on the vgc service and select Properties.
In the "General" tab, find the "Startup type" dropdown menu.
Select
Automaticfrom the dropdown.If the service is currently stopped, click the "Start" button under "Service status".

Applyand thenOKto save the changes.Restart your computer once more to ensure the changes take effect.
Step 3: Addressing Potential Firewall & Antivirus Conflicts
Sometimes, your Windows Firewall or a third-party antivirus program can mistakenly identify Vanguard as a threat and block its connection to the game servers. This can easily lead to the VAN 81 error.
Sub-heading: Allowing Riot and Vanguard Through Windows Firewall
Open the Windows Search bar (by pressing the
Windows key).Type
Windows Defender Firewalland open the application.On the left-hand side, click on
Allow an app or feature through Windows Defender Firewall.Click the
Change settingsbutton.Scroll through the list and look for anything related to League of Legends, Riot Client, or Riot Vanguard.

C:\Program Files\Riot Vanguard.The default path for League of Legends is
C:\Riot Games\League of Legends.Select the executable files (RiotVanguard.exe, LeagueClient.exe, etc.) and click
Add.
Click
OKto save your changes.
Sub-heading: Checking Your Antivirus or Security Software
Open your antivirus software or any security application you have installed.
Look for a section related to "Exclusions," "Exceptions," or "Allow list."
Add the Riot Games and Riot Vanguard folders to this list of exceptions. This tells your antivirus not to interfere with these programs.
You may also need to temporarily disable your antivirus to see if that resolves the issue. If it does, you've found the culprit! You can then configure it to allow Vanguard and League of Legends.
Step 4: A Fresh Start - Reinstalling Riot Vanguard
If the previous steps haven't worked, it's possible that your Vanguard installation is corrupted. A fresh reinstall is often the most reliable way to fix this.
Press the
Windows keyand typeAdd or remove programsand open the system settings.In the list of installed applications, find
Riot Vanguard.Click on it and select

Click the "Update" or "Install" button and let the process complete.
Restart your PC one last time after Vanguard is reinstalled.
Step 5: The Last Resort - Reinstalling the Game
If all else fails, a full reinstallation of League of Legends and Vanguard is the final step. While this can take some time, it ensures that all game files are clean and uncorrupted.
Uninstall both Riot Vanguard and League of Legends from "Add or remove programs" as described in Step 4.
After uninstalling both, delete the
Riot Gamesfolder from your C drive (or wherever you installed the game). This is crucial to remove any lingering corrupted files.Restart your computer.
