How To Fix Error VAN 84 In League of Legends

League of Legends error VAN 84 is one of those issues that usually appears out of nowhere and prevents you from logging into the game or staying connected to Riot’s servers. It’s commonly linked to connection problems, Vanguard issues, or temporary server-side disruptions, which can make it frustrating when everything else on your PC seems fine. Whether the error shows up during launch or mid-session, understanding why VAN 84 happens is the first step to fixing it quickly. In this guide, we’ll walk through what error VAN 84 means, what typically causes it, and the most effective ways to resolve it so you can get back into League of Legends without constant interruptions.

What Causes Error VAN 84 in League of Legends?

Error VAN 84 in League of Legends usually points to a communication problem between your game client and Riot’s servers. One of the most common causes is a temporary server issue or maintenance on Riot’s side, which can block connections even if your internet is working normally. Network instability on your end, such as packet loss, high latency, or brief connection drops, can also trigger VAN 84 because the client fails to maintain a stable link. In some cases, Riot Vanguard may not be running correctly or is being restricted by your firewall or antivirus, preventing proper authentication. Outdated system files, Windows network settings, or background applications that interfere with Vanguard and the Riot Client can also contribute, especially if the error keeps appearing consistently instead of going away on its own.

How to Fix League of Legends Error VAN 84

League of Legends Error VAN 84 is usually temporary, but if it keeps showing up, there are a few proven fixes that can get you back into the game.

Start with the basics. Fully close League of Legends and the Riot Client, then restart your PC. This clears small connection or Vanguard sync issues that often cause VAN 84. After rebooting, launch the Riot Client as an administrator to make sure it has full permissions.

Next, check Riot’s server status. If there’s ongoing maintenance or server instability on Riot Games’ side, VAN 84 can appear even when nothing is wrong on your system. If servers are down, the only fix is to wait.

If servers are online, look at your internet connection. Restart your router, switch to a wired connection if possible, and avoid VPNs or proxies. VPNs are a very common cause of VAN errors because they interfere with Vanguard’s connection checks.

Then, make sure Riot Vanguard is running properly. Press Windows + R, type services.msc, and look for vgc. If it’s stopped, set it to Automatic and start the service. If it won’t start or keeps failing, uninstall Riot Vanguard, restart your PC, and reopen League of Legends so Vanguard reinstalls automatically.

Also check your firewall and antivirus settings. Add exceptions for the Riot Client, League of Legends, and Riot Vanguard. Overly aggressive security software can block Vanguard’s connection and trigger VAN 84.

Finally, ensure Windows is fully up to date. Outdated network or system files can cause communication issues with Riot services. Install all pending updates, restart your PC, and try launching the game again.

If VAN 84 still appears after all these steps, submitting a ticket to Riot Support is the best option, as they can check account-side or regional issues that aren’t visible from your end.
