How to Fix Marvel Rivals “Error Code 211”

Marvel Rivals error code 211 occurs when the game fails to authenticate with Steam. This error typically means the game client is unable to maintain a stable connection with Steam’s servers. Common causes include server outages, network issues, or corrupted local cache and configuration files.

The most frequent cause of this error is corruption in the local configuration files. Marvel Rivals stores essential settings and cached data in these files to speed up performance and reduce load times. However, when this data becomes corrupted, it can prevent the game from verifying your account with Steam.

Before jumping into the fixes, ensure your internet connection is stable. If your connection checks out, continue with the solutions below to resolve the issue.

1. Launch the Game from Steam

If you’re currently launching the game by double-clicking its standalone launcher, try starting it directly through Steam instead. Launching the game via Steam ensures it properly syncs with your Steam account, which helps with authentication and may resolve errors like login error 211.

1. Launch the Steam client on your computer and click on the Library tab at the top.
2. Locate Marvel Rivals in your games list, then click the Play button to start the game.

2. Clear Local Configuration Files

As mentioned earlier, Marvel Rivals stores user settings and game data locally to improve performance and reduce loading times. This setup helps the game fetch frequently used data without repeatedly accessing the server. However, if these local configuration files become corrupted, it can lead to various issues during gameplay or startup.

By clearing the existing configuration files, you allow the game to regenerate fresh, default settings—resolving potential corruption and restoring stable performance.

1. Locate and open the Marvel Rivals Launcher from where you installed the game (typically in your Program Files or game platform’s installation directory).
2. In the launcher window, look for and click the Clear Local Configuration Files button in the bottom left corner.
3. After the process completes, launch the game normally to check if this resolved your error.

3. Verify the Game Files

Verifying the game files scans for any missing or corrupted data and automatically replaces it by downloading a fresh copy from Steam’s servers. This process ensures that all required files are intact and correctly installed. If essential game files are damaged or incomplete, it can prevent Marvel Rivals from launching properly or authenticating the user—so make sure to run a file verification check.

1. Launch the Steam client and go to your Library tab.
2. Right-click on Marvel Rivals in your game list and select Properties from the context menu.
3. In the Properties window:
   • Select Installed Files from the left sidebar
   • Click the Verify integrity of game files button

   

4. Wait for Steam to complete the verification process (this may take several minutes), then launch Marvel Rivals to check if the error persists.

4. Use Google DNS (Domain Name System)

DNS, or the Domain Name System, is responsible for translating domain names into IP addresses, allowing your device to connect to the correct server. If you’re using your ISP’s default or automatic DNS, it might not always be the most reliable. Switching to Google DNS can improve speed, stability, and security when connecting to online services.

1. Click the Start Menu and type Control Panel into the Windows Search Bar.
2. Go to Control Panel > Network and Internet > Network and Sharing Center.
3. From the left pane, click on Change adapter settings.
4. Right-click on your active network adapter and select Properties.
5. Select Internet Protocol Version 4 (TCP/IPv4) from the list, then click Properties.
6. Choose Use the following DNS server addresses and enter the following:
   Preferred DNS server: 8.8.8.8
   Alternate DNS server: 8.8.4.4
7. Click OK to save the settings, then check if the issue has been resolved.

5. Use VPN

If the issue persists, it might be due to network-related problems on your ISP’s end. Using a VPN can help by routing your connection through a different region, which can bypass certain IP restrictions and allow the game to authenticate properly.

Additionally, if the Marvel Rivals servers in your region are overloaded or experiencing temporary issues, a VPN can connect you to a different regional server—potentially avoiding the congestion and resolving the problem.

1. Download and install a free VPN service like Touch VPN (available as a browser extension or standalone app).
2. Launch the VPN and connect to either a USA or Japan server location.
3. With the VPN active, launch Marvel Rivals. If you successfully connect to the game, you can then disconnect the VPN – your connection should remain stable for gameplay.

Final Recommendation: If Marvel Rivals servers are operational and your network connection is stable, we suggest completely reinstalling the game as this will replace any potentially corrupted game files that might be causing connection issues.
