CommonVanguard error

Try these in order

  1. Restart your PC. This gives Vanguard a fresh start.
  2. Check that your Windows date, time and time zone are correct. A wrong clock can break secure connections.
  3. Set the Vanguard service to start automatically: press Win+R, run services.msc, open vgc, set Startup type to Automatic and click Start.
  4. Uninstall Riot Vanguard from Windows Apps, restart your PC, then launch your game so Vanguard installs again.
  5. Do a clean boot to find out whether a background app or service is getting in Vanguard’s way.
  6. Reinstall the game to replace any damaged or missing game files.
  7. If you have a Killer network card, turn off the Killer Network Service.
  8. Work through Riot’s PC connection troubleshooting guide.
  9. Test in the Practice Tool or a custom game, so a repeat of the error doesn’t cost you a ranked match.
Still broken? Restart your PC once more, then contact Riot Support with your logs.

Based on Riot’s official guide.
