Valorant’s Error Code 51 is preventing players from connecting to lobbies in the current patch.
There are a few workarounds available that can help you connect to your games and not get banned due to repeatedly leaving lobbies due to the error.
The error seems to be tied to network connectivity issues and antivirus programs blocking Riot Vanguard from working properly.

Valorant Error Code 51 is preventing players from connecting to games even after finding matches, and it is leading to bans in some cases as the game thinks players are intentionally leaving games. In most cases, the issue has nothing to do with your internet or hardware and it is typically caused by a faulty anti-virus program or corrupt system files in Windows. Here is a quick guide to help you fix Valorant Error Code 51.

Valorant Error Code 51: Disable Your Antivirus

This is the solution that has worked for most players. If you are running an anti-virus program, temporarily disable it before launching Valorant and you should be able to login into the game without getting the error. After you finish your matches, you can re-enable your antivirus. If you use only Windows Defender, you can ignore this step and try the other solutions listed here.

Valorant Error Code 51: Turn off DEP

DEP or Data Execution Prevention is a Windows in-built system-level memory protection feature that protects your system from damage caused by viruses and other security threats. The recent Valorant patch may be conflicting with it and causing errors. Until Riot Games addresses the issue you can consider turning DEP off. It is safe to do so and it does not put your system at risk.

  1. Sign in to Windows as Administrator

  2. Press ‘Windows+R’ and type sysdm.cpl. Hit Enter

  3. Click ‘Advanced’ tab and then click the ‘Settings’ button

  4. Click on Data Execution Protection tab and click ‘Turn on DEP for all programs and services except those I select’

  5. Click ‘Add’ button and then browse and add all the executable (.exe) files that are causing the issue

  6. Click ‘OK’

  7. Restart the system and try running Valorant

Repair Your System Files

If neither of the above solutions work, you can try repairing your system files in Windows. Here’s how to do it:

  1. Press Windows key and type cmd

  2. Right-click on ‘Command Prompt’ and choose ‘Run as Administrator’. A command prompt window appears

  3. Type sfc /scannow and hit Enter key

  4. Let the SFC scan to finish (The repair process is automatic)

If you are still facing issues, you should submit a ticket to Riot Games’ support website for further assistance.
