There is nothing more frustrating than loading into a crucial Ranked game, only to be kicked out before the minions even spawn by a random Vanguard error. You frantically try to reconnect, but the client refuses to cooperate. By the time you fix it, you have received a LeaverBuster penalty and lost your hard-earned LP.
Riot’s Vanguard anti-cheat is deeply integrated into League of Legends in 2026. While it effectively stops scripters, it occasionally conflicts with normal background programs, causing dreaded error codes. If you are stuck in a disconnect loop, here is exactly how to fix the most common Vanguard errors and get back to the Rift.
1. Vanguard Error Code 128 (VAN 128)
This is currently one of the most frequently searched errors. VAN 128 usually means that Vanguard’s core drivers are conflicting with another program on your PC, or your Windows environment is missing specific security features.
The Fix: First, restart your computer—this solves the issue 50% of the time. If the error persists, ensure that “Secure Boot” and “TPM 2.0” are enabled in your motherboard’s BIOS settings, as the 2026 Vanguard system strictly requires them. Finally, disable third-party antivirus software temporarily, as they often falsely flag Vanguard files as malicious.
2. Vanguard Error Code 68 (VAN 68)
If you see VAN 68, the problem is rarely your PC. This error indicates a network timeout between your client and Vanguard’s authentication servers.
The Fix: Do not uninstall the game immediately. First, flush your DNS. Open your Windows Command Prompt as an administrator and type ipconfig /flushdns, then hit Enter. Next, try changing your DNS servers to Google’s public DNS (8.8.8.8 and 8.8.4.4). This usually instantly resolves the routing issue and allows Vanguard to connect securely.
3. The “Waiting for Vanguard” Infinite Loop
Sometimes, there is no error code at all. The client simply gets stuck on a “Waiting for Vanguard to start” screen. This happens when the Vanguard background service (vgc.exe) crashes or fails to launch when Windows boots up.
The Fix: Press Windows Key + R, type services.msc, and press Enter. Scroll down the list until you find the service named “vgc”. Right-click it, select “Properties”, and change the Startup Type to “Automatic”. Click “Start”, then click “Apply”. Restart your League of Legends client, and you should be good to go.
Recovering Your Lost LP
Dealing with technical issues is exhausting, especially when it costs you Ranked games that were completely out of your control. Getting hit by an unfair LeaverBuster penalty or dropping a division because of a VAN 128 error can ruin your entire weekend.
If your MMR took a massive hit due to disconnects and you just want your old rank back without the stressful grind, getting some help is the most efficient solution. Booking a quick solo boost can immediately recover the LP you lost to Vanguard errors. If you want to play the recovery games yourself but want a guaranteed win, hopping into a duo boost with a Challenger partner makes the process incredibly fast. And if your main account is currently locked in a low-priority queue penalty, picking up a premium ranked account allows you to bypass the wait and start playing high-quality games immediately.
