一些玩使命召唤：现代战争或战区^{(Call of Duty: Modern Warfare or Warzone)}的人可能会发现自己处于遇到错误代码664640的位置。只要DNS设置配置不正确，就会出现此错误。此外，Windows 10/11 计算机上的Modern Warfare文件夹可能已损坏。^{(Modern Warfare)}

当玩家尝试启动Modern Warfare 或 WarZone^{(Modern Warfare or WarZone)}时，往往会出现此问题。出现的消息如下：

Error: You have been disconnected, Error Code: 664640

据我们了解，有多个版本可以解决这个问题，我们今天将讨论所有版本。

使命^(Call)召唤：现代战争^{(Modern Warfare)}和战区^(Warzone)是同一款游戏吗？

好的，所以Warzone是 2019 年发布的^(Warzone)现代战争^{(Modern Warfare)}的一部分。但是，它与2020 年发布的《使命召唤：黑色行动^{(Black Ops)}：冷战^{(Cold War)}》直接相关。这里有趣的是，玩家不需要购买《现代战争》^{(Modern Warfare)}或《黑色行动^{(Black Ops)}：冷战》^{(Cold War)}，因为《战区^(Warzone)》是免费的。

^{(Fix Error Code 664640)}修复使命^(Call)召唤现代战争^{(Duty Modern Warfare)}或战区^(Warzone)游戏中的错误代码 664640

解决COD错误代码 664640 不会花费很多时间和精力。以下选项应该足以完成任务：

1. 重新启动您的游戏机和网络硬件
2. 更新您的WarZone和现代战争版本^{(Modern Warfare)}
3. 更改游戏的服务器区域
4. 在 Windows 10 上更改 DNS 设置
5. 更改 Xbox One 上的 DNS 设置

1]重新启动^(Restart)您的游戏机和网络硬件

好的，所以您在这里要做的第一件事就是重新启动您的Xbox One、Windows 10/11 PC 和网络路由器。

要完成此操作，请关闭您的 Xbox One 主机，然后断开电源。对您的网络路由器执行相同操作。重新连接电源线，然后尽快重新启动两个设备。

至于您的计算机，只需以您一贯的方式重新启动计算机即可。完成所有这些后，继续尝试启动游戏，看看是否一切正常。

2]更新^(Update)您的WarZone和Modern Warfare版本^{(Modern Warfare)}

在某些情况下，游戏会因为缺少最新更新而表现不佳。这在Xbox One^{(Xbox One)}和Steam上都很容易解决，所以让我们看看如何解决这个问题。

当涉及到Xbox One版本的游戏时，您必须首先启动控制台。请^(Please)从主屏幕按控制器上的Xbox按钮，然后导航到^(Xbox)Profile & system > Settings > System > Updates。

从这里开始，WarZone和Modern Warfare以及其他所有游戏现在应该会自动更新。

至于Steam，就很不一样了，显然平台和 Xbox 不一样。请^(Please)从您的 Windows 10/11 PC 上打开Steam 客户端^{(Steam client)}，并确保单击顶部菜单中的库^(Library)。在您的库中找到受影响的游戏，然后右键单击每个游戏并从弹出菜单中选择属性。^(Properties)

最后，点击更新^(Updates)选项卡，如果有可用的更新，游戏应该立即下载最新的更新。

3]更改^(Change)游戏的服务器区域

您^(Did)知道可以更改服务器区域吗？如今，在许多使用专用服务器的游戏中，用户可以在不同地区的服务器之间跳转以获得更好的性能。例如，如果您居住在亚洲^(Asia)，那么您最好从您所在地区而不是北美^{(North America)}选择服务器。

要对使命召唤标题进行此更改，请^(Call)打开^(Duty)战网^(Battle.net)启动器，然后选择现代战争^{(Modern Warfare)}。从那里，选择靠近播放按钮的^(Play)齿轮^(Gear)图标，然后选择区域^(Regions)。

从可用列表中选择您的首选区域，完成此操作后，您可以继续检查错误代码 664640 是否仍然存在问题。

4]在PC上更改DNS设置

停止此错误可能是由于您在Windows 10上的^{(Windows 10)}DNS配置存在问题。我们建议将您的 DNS 设置更改^{(changing your DNS settings)}为更可靠的设置。文章建议使用Google DNS服务器，但我个人认为最好利用OpenDNS服务器。

以下DNS服务器链接到OpenDNS：

• 208.67.222.222
• 208.67.220.220。

5] 更改 Xbox One 上的 DNS 设置

更改 Xbox One^{(Changing the DNS settings on the Xbox One)}视频游戏控制台上的 DNS 设置是您可以考虑的另一种选择。

Fix Error Code 664640 in Call of Duty Modern Warfare or Warzone game

Some folkѕ who play Call of Duty: Modern Warfare or Warzone, might find themselves in a position where they come across error code 664640. This error tends to arrive whenever the DNS setting is not configured properly. Additionally, the Modern Warfare folder on your Windows 10/11 computer is probably corrupted.

The issue tends to arise when the gamer attempts to launch Modern Warfare or WarZone. The message that appears is as follows below:

Error: You have been disconnected, Error Code: 664640

From our understanding, there are multiple versions to fix this problem, and we are going to talk about all of them today.

Is Call of Duty: Modern Warfare and Warzone the same game?

OK, so Warzone is part of Modern Warfare which was released back in 2019. However, it is directly connected to Call of Duty: Black Ops: Cold War, a title released in the year 2020. What’s interesting here, is the fact that players are not required to purchase either Modern Warfare or Black Ops: Cold War seeing as Warzone is free-to-play.

Fix Error Code 664640 in Call of Duty Modern Warfare or Warzone game

Solving COD error code 664640 will not take a lot of time and effort. The following options should be enough to accomplish the task:

1. Restart your gaming machine and networking hardware
2. Update your version of WarZone and Modern Warfare
3. Change the server region of your game
4. Change DNS settings on Windows 10
5. Change DNS settings on Xbox One

1] Restart your gaming machine and networking hardware

OK, so the first thing you want to do here is to restart your Xbox One, Windows 10/11 PC, and network router.

To get this done, please turn off your Xbox One console, then unglue the power source. Do the same with your network router. Reconnect the power cable, then restart both devices as soon as possible.

As for your computer, simply restart your computer in the way you’ve always done. After you’ve accomplished all of that, go ahead and attempt to launch the game(s) to see if things are working as they should.

2] Update your version of WarZone and Modern Warfare

In some scenarios, the games are acting up because they lack the latest update. This is easily fixable on both the Xbox One and Steam, so let us look at how to solve this matter.

When it comes down to the Xbox One version of the game, you must first fire up the console. Please press the Xbox button on the controller from the main screen, then navigate to Profile & system > Settings > System > Updates.

From here on, WarZone and Modern Warfare, along with every other title, should now automatically update themselves.

As for Steam, it’s very different, seeing the platform is not the same as Xbox, obviously. Please open the Steam client from your Windows 10/11 PC and be sure to click on Library from the top menu. Locate the affected games in your library, then right-click on each and select Properties from the pop-up menu.

Finally, hit the Updates tab, and right away, the game should download the newest update if there are any available.

3] Change the server region of your game

Did you know it is possible to change the server region? In many games these days with dedicated servers, users can jump between servers from different regions for better performance. For example, if you reside in Asia, then you would be better off selecting a server from your area instead of North America.

To make this change for Call of Duty titles, please open the Battle.net launcher, then select Modern Warfare. From there, select the Gear icon that is located close to the Play button, then choose Regions.

Select your preferred region from the list available, and once you’ve done that, you can go on ahead and check if error code 664640 is still an issue.

4] Change DNS settings on PC

Stopping this error could be due to problems with your DNS configuration on Windows 10. We suggest changing your DNS settings to something more reliable. The article suggests the use of Google DNS servers, but personally, I believe it is best to take advantage of OpenDNS servers.

The following DNS servers are linked to OpenDNS:

• 208.67.222.222
• 208.67.220.220.

5] Change DNS settings on Xbox One

Changing the DNS settings on the Xbox One video game console is another option that you can consider.
