How to fix Black Ops 6 ‘Our level fastfile is different from the server’ error

Every major game release these days comes with a plethora of error codes and it's no different with Call of Duty: Black Ops 6.

While Black Ops 6's worldwide release has been going smoothly thus far, one error code in particular is causing distress to players. The error message in question is "Our level fastfile is different from the server! Aborting connection."

Although it's frustrating, don't panic as it's very easy to fix "Our level fastfile is different from the server" error in Black Ops 6.

To fix this, simply restart Black Ops 6. You can do this by shutting down the app altogether or via the in-game menu. When I got this message in the first hours of my Black Ops 6 playthrough, it was followed by an "update requires restart" message.

By all looks of this, the "Our level fastfile is different from the server" error only pops up when you try to access multiplayer. This message means that there's a connection error between the Black Ops 6 servers and your game.

If you're getting the "Our level fastfile is different from the server" error constantly, you could also try to restart your PC or console, and your internet modem.

Though pesky errors like this are annoying, the developers usually fix them in the first 48 hours to avoid unnecessary bad PR. The odds are that Treyarch and Activision are looking into this as you read this article.

Now that you know how to fix this and continue playing Black Ops 6, you can also check out how to unlock every weapon in the game and start grinding multiplayer lobbies.
