Some Warzone 2 dev error codes including the error 657 can sometimes occur due to corrupted game files or bad local files of the game. At other times, random errors may be triggered by a minor glitch in the system or in the game client. 

If you’re getting the Warzone 2.0 error code 657 out of the blue and you have no idea how to go about it, these are the solutions that you should try.

Checking for updates is a good first step in fixing the Warzone 2 dev issue 657.

Multiplayer in a demanding game like Call of Duty Warzone 2.0 requires a fast Internet connection, and if you don’t have one, the game will give you an error message. Check your connection speed using an online tool, and if it’s slow, try restarting your router. Start up the game, get on the online mode, and see whether the connection holds up. If it continues, you should call your Internet service provider.

Fix #4: Verify game files.

Bad or corrupted game files can impact the performance of a game and in some cases, even cause crashing or launching issues. Fortunately, it’s very easy to repair game files.

We suggest checking the game files for corruption as a first step in fixing the problem. Launch Steam and head to the Library to see if your copy of Warzone has been corrupted. Select “Properties” from the menu that appears after right-clicking the game tag. You may check the game’s files for corruption by going to the Local Files tab and clicking the Verify integrity of game files button.
