VAN 1 in Valorant means Vanguard can't connect to Riot's servers. This is a network issue between your PC and Riot's anti-cheat infrastructure.
How to fix it:
- Check Riot Games server status at status.riotgames.com — if servers are down, just wait
- Disable any VPN or proxy — Vanguard has issues with some VPN software
- Make sure Windows Firewall isn't blocking Vanguard: open Windows Security > Firewall > Allow an app, and ensure Vanguard (vgc) is allowed on both Private and Public networks
- Flush your DNS: open Command Prompt as Admin and run 'ipconfig /flushdns'
- Try switching DNS servers to Cloudflare (1.1.1.1) or Google (8.8.8.8)
- Restart the Vanguard service: open Services (services.msc), find 'vgc', right-click > Restart
- Disable any third-party firewall or security suite temporarily to test
- If on a university or corporate network, they may be blocking Riot's anti-cheat traffic — try a mobile hotspot to confirm
