Call of Duty Black Ops 6 players often run into the “failed to join because of different version” error every time the shooter receives a massive update in the form of a new season drop. It’s one of the more annoying performance issues that can be fixed by employing a couple of methods
So if you are running into it quite a bit, the guide below will be able to help you out.
How to fix the “failed to join because of different version” error in Black Ops 6

The “different version” error message pops up when you are trying to join a party from the lobby screen. The two standard fixes that you can try for this will be the following:
- Restarting the game.
- Installing the latest patch, keeping BO6 up to date.
However, even after completing the two methods the error persists, you can try the following:
1) Join your friends after connecting to a “Recent Players” lobby
According to the Reddit post, one neat trick that you can try to solve the version error is to join a recent player’s lobby. You can do this from the ‘Recent Players’ hub in the Social tab and pick any active lobby.
Once you join the random lobby, try joining the lobby that your friend has made. This will bypass the error in most cases. However, if the message pops up again, make sure to quit the random lobby immediately if you want to play with your friends.
2) Clear “Reserved Space” data (Xbox-exclusive)
Those enjoying Call of Duty Black Ops 6 on an Xbox can try clearing their game data and restarting the shooter. You can do this by:
- Making your way to the ‘Manage Game & Add Ons’ on your game file
- Then select “Saved Data”
- Click on “Reserved Space”.
- Finally, pick “Clear Reserved Space”.
Once you do this, your console will refresh and likely allow you to join a friend’s lobby.
3) Everyone in your lobby needs to restart BO6
While it might not look like much of a fix many in the community have stated that if you and every friend in your lobby restart the game and try again, then it’s likely going to bypass the version error that you are facing.
