Valorant VAN 84 Fix: Connection Error & Vanguard Timeout Solved
Tested & peer-reviewed by the GameFixDB Systems & Anti-Cheat Lab for Valorant (VAN 84).
Valorant Error Code VAN 84 is a network heartbeat timeout between the local Riot Vanguard kernel driver (vgk.sys) and Riot's session coordinator. It occurs during brief ISP routing hiccups or when the Windows vgc service stalls.
- ▸Set the Vanguard 'vgc' service to Automatic startup in Windows Services (services.msc)
- ▸Run 'netsh winsock reset' and flush DNS cache in an administrator Command Prompt
- ▸Restart your home router and connect via wired Ethernet cable rather than Wi-Fi
Step-by-Step Resolution Steps
Click steps to track progressEnsure Vanguard Service (vgc) is Running and Set to Automatic
If Windows suspends or delays the vgc service, Valorant drops the session heartbeat and kicks you to desktop with VAN 84.
cmd /c sc config vgc start=auto && sc start vgcReset Windows Winsock Sockets & Flush DNS Resolver
Purging corrupt TCP/IP network states restores steady UDP stream connectivity to Riot's edge datacenters.
cmd /c netsh winsock reset && ipconfig /flushdnsSwitch to Low-Latency Cloudflare DNS Resolvers
Configure IPv4 DNS to 1.1.1.1 and 1.0.0.1 to eliminate DNS lookup timeouts to Riot's session servers.
powershell -Command "Get-NetAdapter | Where-Object {$_.Status -eq 'Up'} | Set-DnsClientServerAddress -ServerAddresses ('1.1.1.1','1.0.0.1')"Did these steps resolve your error?

Pro Esports Advisory: Preventing Recurrence in Valorant
Professional tournament players tune their Windows environment to prevent sudden runtime crashes, memory leaks, and 1% low frame stuttering:
Never immediately jump into a ranked queue after a driver or game update. Wait 2-3 minutes at the main menu until the shader compilation pipeline reaches 100% to avoid mid-round micro-freezes.
Turn off "Hardware Acceleration" in Discord, Chrome, and Spotify. Background apps using your GPU video decoder compete with the game engine for DirectX video memory (VRAM) handles.
Avoid powerline adapters and mesh Wi-Fi nodes during competitive matches. Direct Cat 6/Cat 8 Ethernet eliminates packet jitter drops that trigger anti-cheat server timeouts.
Why Does This Error Happen?
Understanding the root cause prevents recurrence during competitive matches:
- 1Riot Vanguard 'vgc' background service stalling or set to manual startup in Windows Services
- 2Micro packet loss or high jitter standard deviation on local Wi-Fi or ISP routing nodes
- 3Windows Firewall or third-party antivirus blocking Riot Vanguard outbound port handshakes
- 4Riot Games session gateway temporary downtime during matchmaking updates

Frequently Asked Questions (VAN 84)
Does VAN 84 mean Riot Vanguard detected third-party software?
No. VAN 84 is purely a network connection and communication heartbeat failure. It does not indicate an anti-cheat ban or strike on your account.
Can I reconnect to a competitive match after getting VAN 84?
Yes. Once you execute the vgc restart command and relaunch the Riot Client, you can reconnect directly back into your ongoing match without an AFK penalty if done within 3 minutes.
