When it comes to fixing the Version mismatch error in “Rocket League,” all you need to do is press a few buttons (courtesy of the “Rocket League” support page.) The Version Mismatch error pops up anytime the game hasn’t been updated to its most recent version. The online game is unable to be played if you don’t have the newest version of “Rocket League,” so you’ll need to update your game.
The most “difficult” part of the entire process is figuring out where the game update is. Most systems will ask players to update the game during launch. If the game isn’t asking you to update it whenever you launch it, restart your console and try again. Once that’s done, voila! The error should go away.
Mismatch error makes sense, as players with different versions of the game might have certain advantages or disadvantages against others. By requiring players to update “Rocket League” before engaging in online play, developers help create an even playing field for gamers.
