How to Fix Valorant Error Code Van 79 in 10 Ways

Quick Steps

When you launch Valorant, an error shows "VALORANT has encountered a connection error. Please relaunch the client to reconnect. Error Code: VAN-79." This is unusual and not on the list of Valorant error codes. What is it?

What Is VAN 79 in Valorant?

VAN-79 is an error that typically occurs when Valorant can't properly initialize Riot Vanguard, its mandatory anti-cheat component, or fails to establish a secure connection to Riot's servers during game launch.

Vanguard Service (VGC) Fails to Start

• If the VGC service is stopped, disabled, or set to manual setup, Vanguard cannot initialize, and Valorant throws VAN-79.
• In rare cases, Windows Secure Booot or system policies might block Vanguard from starting due to driver signing enforcement.

Corrupted or Interrupted Vanguard Updates

• Partial Vanguard updates, especially after installing Valorant on a different drive, often break the connection between game files and the anti-cheat system.

Interference from Other Software

• Conflicts with third-party programs like Cheat Engine, audio drivers, or even Discord overlays have been reported to trigger VAN‑79

Bad Network or System Configuration

• Misconfigured network settings, leftover DNS or Winsock entries, and firewall/antivirus restrictions can block Vanguard's communication, leading to VAN‑79.

Account Session Issues

• Occasionally, persistent login credentials or a corrupted Riot Client session can break authentication, resulting in this error

How to Fix VAN-79?

1. Restart Your PC

A simple reboot can reinitialize Vanguard and clear temporary issues.

2. Ensure Riot Vanguard Service Is Running

• 1. Open cmd on your computer and enter services.msc
• 2. Find vgc and double-click it.
• 3. Click Start if the Service status stops.
• 4. Then choose Automatic for Startup type.
• 5. Hit Apply.

• 6. Repeat steps for Virtual Disk.

• 7. Then, run the command prompt as an administrator.
• 8. Enter the following commands one by one:

1. bcdedit.exe /set testsigning off
2. bcdedit.exe /set nointegritychecks off

• 9. Launch Valorant, click the profile, and go to TWO-FACTOR AUTHENTICATION > LOG OUT EVERYWHERE > CONFIRM.

• 10. Close Valorant and exit it from the screen's bottom.
• 11. Open the RIOT GAMES client and log in again.

3. Reset Network Settings & Flush DNS

• 1. Log out of the account from all devices.
• 2. Set the Riot Client and Valorant to run as Admin using compatibility options.
• 3. Open Command Prompt (Admin) and run each code:

1. netsh winsock reset 
2. ipconfig /flushdns 
3. netsh int ip reset 
4. ipconfig /release 
5. ipconfig /renew 

• 4. Then restart your PC to refresh network connections.

4. Run as Administrator

Right-click the Valorant shortcut > Properties > Compatibility tab > check Run this program as administrator and disable fullscreen optimizations.

5. Update Windows & Drivers

Ensure both Windows and network drivers are fully updated via Device Manager and Windows Update.

🪟 A. Update Windows OS

• 5. If an update is found, follow the prompts. If not, consider checking your manufacturer's website for the latest version.

6. Network Reset

A network reset wipes out old configurations, clears any lingering conflicts, and resets components like the DNS cache, Winsock, and IP stack—often fixing hidden causes of VAN-79.

How to Reset Your Network Settings:
