2) Check for updates on your Xbox

While rare, Xbox users may encounter a version mismatch between client and server error if an update hasn’t been automatically downloaded. You can manually check and install updates by following these steps:

• Press the Xbox button to open your library.
• Locate Marvel Rivals, then click More Options.
• From the dropdown menu, select Manage Game & Add-Ons.
• Navigate to the Updates tab and download any available updates.
• Once the update is installed, restart your Xbox and relaunch the game.

3) Check your internet connection

An unstable internet connection can also cause the version mismatch error, as interruptions may prevent the game client from syncing with the server. Here’s how to ensure a stable connection:

• Use an Ethernet cable instead of Wi-Fi for a more reliable connection.
• Check your internet connection to ensure it’s working properly.
• If issues persist, restart your router or contact your service provider.
