您的计算机上的 Steam 中是否出现服务器通信错误^{(server communication error in Steam)}？很有可能是您的自动LAN设置导致了该问题。其他项目也可能导致 Steam 显示此错误消息。以下是在Windows^(Windows)和Mac上解决此问题的几种方法。

除了无效的LAN设置之外，其他可能导致Steam显示上述错误的因素还有Steam自身的小故障、服务器停机、VPN被阻止、防火墙阻止Steam访问互联网等等。

1.检查Steam的服务器状态

当您收到上述错误时，首先要检查的是 Steam 的服务器状态。该平台的服务器可能会停机，导致应用程序的各种功能不可用。

您可以前往DownDetector^{(Downdetector)}等网站检查Steam是否面临中断。如果该网站说Steam有服务器问题，您必须等到该公司修复这些问题。

2.强制关闭^{(Force Close)}并重新打开Steam^{(Reopen Steam)}以修复错误通信^{(Error Communicating)}问题

Steam 的小故障可能会导致应用程序无法连接到服务器。在这种情况下，请在 Windows 或Mac^(Mac)计算机上强制退出并重新启动该应用程序以解决您的问题。

在 Windows 上

1. 打开“开始”^(Start)菜单，找到“任务管理器”^{(Task Manager)}，然后启动该实用程序。
2. 右键单击列表中的Steam ，然后选择^(Steam)“结束^(End)任务”以关闭Steam。

1. 在您的 PC 上重新启动 Steam。

在 macOS 上

1. 按Mac 键盘上的 Option + Command + Esc
2. ^{(Select Steam)}在列表中选择 Steam ，然后选择“强制退出”^{(Force Quit)}。
3. 在 Mac 上重新打开 Steam 应用。

3.以管理员身份运行Steam

Steam 无法与其服务器通信的^{(Steam fails to communicate with its servers)}原因之一是应用程序没有运行所需的权限。在这种情况下，您可以以 admin 身份运行应用程序^{(run the app as admin)}，为应用程序提供正常运行所需的所有权限。

请注意，您只需在Windows PC 上执行此操作。

1. 打开“开始”并找到 Steam。
2. 右键单击^{(Right-click)}该应用程序并选择以管理员身份运行^(Run)。

1. 在用户帐户控制^{(User Account Control)}提示中选择是^(Yes)。

4. 通过禁用 VPN 来修复 Steam

VPN应用程序通过第三方服务器路由您的互联网流量，从而更改您的 IP 地址和位置。^(VPN)有时，这些VPN^(VPNs)无法与Steam等支持互联网的应用程序很好地配合。

在这种情况下，请关闭您的VPN服务，看看是否可以解决问题。您可以通过打开VPN应用程序并关闭主界面上的选项来禁用您的服务。

然后，启动Steam客户端并查看您的问题是否得到解决。

5.禁用电脑的自动 LAN 设置^{(Automatic LAN Settings)}

Windows 提供了一个选项，可以自动检测 LAN （局域网）^{(Local Area Network)}设置并将其应用^{(automatically detects and applies LAN)}到您的 PC。此功能可能出现故障，导致 Steam 无法连接到其服务器。

您可以关闭该 Windows 选项来解决您的问题。

1. 打开“开始”^(Start)菜单，找到“Internet 选项”^(Options)，然后启动该项目。

8 Ways to Fix Steam’s Communicating With Server Error

Do уou get a server communication error in Steam on your computer? There’s a good chance your automatic LAN settings are causing the problem. Other items can also lead Steam to display this error message. Here are a few ways to get around this problem on Windows and Mac.

In addition to invalid LAN settings, other items that can cause Steam to display the above error are Steam’s own minor glitches, server downtime, a blocked VPN, a firewall blocking Steam’s access to the internet, and more.

1. Check Steam’s Server Status

When you get the above error, the first thing to check is Steam’s server status. The platform’s servers may be experiencing downtime, causing the app’s various features to become unavailable.

You can head to a site like Downdetector to check if Steam is facing outages. If the site says that Steam has a server issue, you’ll have to wait until the company fixes those issues.

2. Force Close and Reopen Steam to Fix the Error Communicating Issue

Steam’s minor glitches can cause the app to not connect to the servers. In this case, force-quit and relaunch the app on your Windows or Mac computer to resolve your problem.

On Windows

1. Open the Start menu, find Task Manager, and launch the utility.
2. Right-click Steam on the list and choose End task to close Steam.

1. Restart Steam on your PC.

On macOS

1. Press Option + Command + Esc keys on your Mac’s keyboard.
2. Select Steam on the list and choose Force Quit.
3. Reopen the Steam app on your Mac.

3. Run Steam As Admin

One reason Steam fails to communicate with its servers is that the app doesn’t have the required permissions to function. In this case, you can run the app as admin, giving the app all the permissions it needs to run properly.

Note that you only have to do this on a Windows PC.

1. Open Start and find Steam.
2. Right-click the app and choose Run as administrator.

1. Select Yes in the User Account Control prompt.

4. Fix Steam by Disabling Your VPN

A VPN app routes your internet traffic through a third-party server, changing your IP address and location. Sometimes, these VPNs don’t work well with your internet-enabled apps like Steam.

In this case, turn off your VPN service and see if that fixes the issue. You can disable your service by opening your VPN app and toggling off the option on the main interface.

Then, launch the Steam client and see if your issue is resolved.

5. Disable Your PC’s Automatic LAN Settings

Windows offers an option that automatically detects and applies LAN (Local Area Network) settings to your PC. It’s possible this feature is malfunctioning, preventing Steam from connecting to its servers.

You can toggle off that Windows option to resolve your issue.

1. Open the Start menu, find Internet Options, and launch that item.
2. Access the Connections tab and select the LAN settings button.

1. Disable the Automatically detect settings option.

1. Select OK, Apply, and then OK on the open windows.
2. Quit and reopen Steam on your PC.

6. Flush Your Computer’s DNS Cache

Your computer caches DNS data to help your internet-enabled apps quickly translate domain names to IP addresses. This cache may have gone corrupt, causing Steam unable to resolve domain names to IPs.

In this case, flush your Windows or Mac machine’s DNS cache, and your issue will be resolved. Note that you won’t lose your Steam or any other data while clearing your DNS cache.

On Windows

1. Open Start, find Command Prompt, and select Run as administrator.
2. Choose Yes in the User Account Control prompt.
3. Enter the following command on the CMD window and press Enter: ipconfig /flushdns

1. After the DNS cache is cleared, run the following commands, one at a time.
   
   ipconfig /release
   ipconfig /renew
   
2. Close Command Prompt and launch Steam.

On macOS

1. Open a Terminal window on your Mac.
2. Type the following command in Terminal and press Enter:
   sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder
3. Type your Mac’s admin password and press Enter. Terminal won’t display the password but type it anyway.

7. Allow Steam Through Your Firewall

Your machine’s firewall may have blocked Steam’s access to the internet, causing the app unable to communicate with its servers. You can verify this by temporarily turning off your firewall. If Steam then succeeds in connecting to its servers, you can add the app to your firewall’s whitelist so your firewall always allows Steam to connect to the internet.

On Windows

1. Open Start, find Windows Security, and open the app.
2. Select Firewall & network protection in the app.
3. Choose the network saying (active).
4. Disable the Microsoft Defender Firewall toggle.

1. Select Yes in the User Account Control prompt.
2. Open the Steam app.

If Steam connects to its servers after disabling the firewall, add the Steam app to your firewall’s allowlist, as explained below:

1. Open Windows Security and select Firewall & network protection.
2. Choose Allow an app through firewall.

1. Select Change settings at the top.
2. Enable the checkbox beside Steam on the app list.

1. Turn on both Private and Public checkboxes for Steam.
2. Select OK at the bottom to save your changes.

On macOS

1. Select the Apple logo in your Mac’s top-left corner and choose System Preferences.
2. Select Security & Privacy on the following page.
3. Open the Firewall tab.
4. Select the padlock icon at the bottom, enter your Mac’s admin username and password, and select Unlock.
5. Select the Turn Off Firewall button.
6. Launch the Steam app.

8. Uninstall and Reinstall Steam

If Steam still displays an error that says the app has issues communicating with its servers, your last resort is to remove and reinstall the app on your computer. Doing so removes all of the app’s files, some of which may be problematic, causing the above issue.

Reinstalling the app brings new files, allowing you to launch and use the app without any issues.

On Windows

1. Open Settings by pressing Windows + I.
2. Select Apps on the left and Apps & features on the right.
3. Select the three dots next to Steam on the list and choose Uninstall.

1. Select Uninstall in the prompt to confirm your choice.
2. Reinstall Steam from the app’s official site.

On macOS

1. Open Finder and select Applications in the left sidebar.
2. Find Steam on the right pane, right-click the app, and choose Move to Trash.
3. Reinstall Steam from its official site.

Troubleshooting Steam’s Communicating With Server Error

There are various reasons Steam fails to communicate with its servers. Once you identify and fix the underlying item, Steam should have all the access it needs to function on your computer.

We hope the guide above resolves your Steam error, so you can get back to playing your favorite games. Happy gaming!
