How to Fix: VALORANT Error 43

Quick Fix

Error 43 almost always clears up with a simple restart sequence:

1. Fully close VALORANT and the Riot Client (check Task Manager for lingering RiotClientServices.exe or VALORANT.exe processes and end them).
2. Relaunch the Riot Client, wait for it to fully load, then open VALORANT again without alt-tabbing.
3. If it still fails, restart your PC entirely, then try once more.

Step-by-Step Guide

What VALORANT Error 43 Means

Error 43 displays the message “There was an error connecting to the platform. Please restart your game client.” It appears when the VALORANT/Riot Client fails to establish a connection to Riot’s platform servers within the expected time. It is officially listed as a known error code on Riot’s support error-code page, and is generally treated as a connectivity or client-communication issue rather than an account ban or hardware fault.

Common underlying causes include: temporary Riot server downtime or maintenance, an unstable or slow internet connection, corrupted or conflicting Riot Client settings files stored in your AppData folder, the Vanguard anti-cheat service not running, or simply alt-tabbing/multitasking while the client is trying to load its main menu.

Step-by-Step Fixes (Windows PC)

1. Restart the client without multitasking. A very common trigger is alt-tabbing while VALORANT loads. Close the client completely, reopen it, and let it sit untouched until the main menu fully loads before switching windows or apps.
2. Restart your PC. If a plain client restart doesn’t work, reboot your computer entirely to clear out any stuck background processes that may be interfering with the Riot Client, then relaunch VALORANT.
3. Check Riot’s server status. Before troubleshooting further, visit the Riot Games service status page and select VALORANT to see if there’s ongoing maintenance or an outage — if so, you’ll simply need to wait it out.
4. Check your internet connection. Test your connection speed and stability, and restart your router if needed, since a weak or interrupted connection can prevent the client from reaching Riot’s servers.
5. Delete the Riot Client private settings file. This is one of the most frequently cited fixes: press Win + R, type %AppData%, press Enter, then navigate to Local > Riot Games > Riot Client > Data. Delete the file named RiotClientPrivateSettings.yaml (sometimes called RiotClientSettings.yaml), then relaunch VALORANT as an administrator — it will regenerate the file and prompt you to sign in again.
6. Make sure Vanguard is running. Open the Run dialog (Win + R), type services.msc, and press Enter. Find the service named vgc in the list, double-click it, set Startup type to Automatic, and click Start if it isn’t already running. Vanguard must be active for VALORANT to launch.
7. Repair the game files via the Riot Client. Open the Riot Client, click the gear/settings icon in the top-right corner, and use the Repair option to scan for and fix corrupted installation files.
8. Try compatibility troubleshooting. Navigate to C:Riot GamesRiot Client, right-click RiotClientServices.exe, and select Troubleshoot compatibility to let Windows detect potential conflicts.
9. Flush DNS and reset network settings. Open Command Prompt as administrator and run ipconfig /flushdns followed by a Winsock reset command, then restart your PC — this clears out stale cached network data that can interfere with connections.
10. Update network drivers. Outdated network adapter drivers can contribute to connectivity errors; check Windows Update or your PC/motherboard manufacturer’s site for the latest driver.
11. Reinstall Riot Vanguard. If Vanguard itself seems corrupted, close all Riot processes, delete the Riot Vanguard folder from Program Files, empty the Recycle Bin, then relaunch VALORANT as administrator so Vanguard reinstalls fresh.
12. Uninstall and reinstall VALORANT as a last resort. Go to Control Panel > Uninstall a program, remove VALORANT, then download and reinstall it fresh from Riot’s official website. Do not manually delete or tamper with individual game files, as this can create new corruption issues rather than fixing them.

When to Seek Further Help

If you’ve restarted, verified server status, cleared the settings file, confirmed Vanguard is running, repaired files, and even reinstalled the game with no luck, the issue may be tied to your specific account, ISP-level restrictions, or a broader Riot server-side problem. In that case, submit a support ticket through Riot’s official VALORANT support site (email verification on your Riot account is required to do this), and keep an eye on Riot’s Discord or Support Site banners for announcements about ongoing outages. Note that all file-path and service steps above (AppData, services.msc, Control Panel) are Windows-specific; PS5 users experiencing this error should instead focus on restarting the console, checking PSN/Riot server status, verifying internet connection, and reinstalling the app if needed, since the AppData and Vanguard service fixes do not apply on console.
