Valorant Error Code 0 is a general connection error that typically appears when the Riot Client loses contact with Riot's servers or encounters an internal networking issue. This can be triggered by a bad internet connection, a corrupted client session, firewall interference, or temporary server-side problems. In most cases, you can resolve it yourself in just a few minutes by restarting the client and checking your network.

Tools You'll Need

How to Fix Error Code 0

  1. Restart the Riot Client Completely

    Do not force-quit the Vanguard anti-cheat process repeatedly in a short span — this can sometimes trigger additional errors. Simply end it once through Task Manager.

  2. Check Riot's Server Status

  3. Restart Your Router and Modem

  4. Flush DNS Cache and Renew IP Address

    Running these commands will temporarily disconnect your internet for a moment. Make sure you are not in the middle of any other important downloads or calls.

  5. Allow Valorant and Riot Client Through Your Firewall

  6. Temporarily Disable Third-Party Antivirus or VPN

    Only disable antivirus software briefly for testing. Re-enable it as soon as you have confirmed whether it was the cause. Do not play games with antivirus permanently disabled.

  7. Reinstall the Riot Client

    Uninstalling the Riot Client will not delete your Valorant account or in-game progress. Your account data is stored on Riot's servers. However, the game files will need to be re-downloaded, which may take significant time depending on your internet speed.

When to Call a Professional

Valorant Error Code 0 is almost always a software or network issue that you can resolve yourself. However, if you have tried all the steps above and still cannot connect, consider contacting Riot Games Support directly at support.riotgames.com — they can review your account status, check for region-specific outages, or identify if your account has been flagged. If multiple games and apps cannot connect to the internet simultaneously, the issue may be with your ISP, in which case contact your internet service provider for assistance.
