您在 Windows 或Mac上使用 Steam 时是否遇到无连接错误^{(no connection error while using Steam)}？您的游戏客户端可能会遇到连接互联网的问题，从而导致出现上述错误消息。您可以应用一些解决方案来解决该问题，我们将向您展示这些解决方案是什么。

虽然Steam 无法连接到互联网的^{(Steam can’t connect to the internet)}原因有很多，但最主要的原因是您的互联网连接有问题、Steam已关闭、您正在使用VPN以及您的防火墙阻止了Steam访问互联网。

检查您的互联网连接

当您遇到网络问题时，您的互联网连接是第一个要检查的项目。例如，您的连接可能已断开，导致 Steam 无法连接到平台的服务器。

您可以通过在桌面上打开 Web 浏览器并启动网站来验证这一点。如果您的网站无法加载，则表明您的互联网连接有问题。在这种情况下，请按照以下基本解决方案来解决您的互联网问题。

重新启动路由器

您的互联网路由器可能遇到小问题，导致您的互联网无法工作。在这种情况下，请重新启动路由器^{(give your router a reboot)}以修复设备的许多小问题。

您可以通过按设备上的电源按钮来重新启动大多数路由器。^(Power)某些路由器允许您从设备的设置菜单重新启动，您可以通过计算机的网络浏览器访问该菜单。在此方法中，您将选择“提交”^(Commit)和“重新启动”^(Reboot)等选项来重新启动路由器。

当您的路由器重新启动时，启动Steam并查看是否仍然出现相同的错误。

更新您的网络适配器驱动程序^{(Network Adapter Drivers)}

您的计算机的网络适配器是您连接到互联网的方式。该适配器可能使用过时的驱动程序^{(This adapter may be using outdated drivers)}，导致您的互联网连接出现问题。在这种情况下，请使用 Windows PC 的设备管理器^{(Device Manager)}实用程序查找并安装适用于您的适配器的最新驱动程序。

您不必在Mac上执行此过程。

1. 右键单击^{(Right-click)}“开始^(Start)”菜单图标并选择“设备管理器”^{(Device Manager)}。
2. 展开网络^{(Expand Network)}适配器，右键单击您的适配器，然后选择更新^(Update)驱动程序。

1. 选择^{(Select Search)}自动搜索驱动程序。
2. 允许该工具安装可用的驱动程序。
3. 重新启动您的电脑并启动 Steam。

检查 Steam 网络是否已关闭

Steam 的服务器可能遇到中断，导致您的 Steam 客户端无法连接到这些服务器。您可以使用一些第三方网站检查是否属于这种情况。

您可以使用Down detector^{(Downdetector)}等网站来检查用户是否报告了使用Steam 的^(Steam)问题。您可以使用非官方 Steam 状态站点来验证^{(unofficial Steam Status)}Steam是否已关闭。Steam 的非官方 Twitter 帐户^{(Steam’s unofficial Twitter account)}也是检查平台中断情况的好地方。

如果平台出现故障，您将不得不等待公司修复问题。您无法采取任何措施来解决问题。

重新启动您的 Windows 或Mac 计算机^{(Mac Computer)}

如果Steam仍然显示无连接错误，则您的 Windows 或Mac计算机可能存在小故障。这些操作系统上存在此类小问题是很常见的，您可以通过重新启动计算机^{(rebooting your computers)}来修复它们。

这样做会关闭并重新加载所有系统功能，从而修复许多小问题。

以管理员身份运行 Steam

Steam 无法连接到互联网，因为该应用程序可能没有所需的权限。当您在没有管理权限的情况下运行应用程序时，通常会发生这种情况。

您可以通过在管理模式下启动应用程序^{(launching the app in admin mode)}并授予其运行所需的所有权限来解决此问题。这应该会消除您的Steam连接错误。

1. 右键单击 Steam 的桌面快捷方式，然后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)。

如果以管理员身份运行应用程序后修复了 Steam 的无连接错误，请按照以下步骤让Windows始终以管理员权限启动应用程序：

2. 选择快捷方式^(Shortcut)选项卡并选择高级^(Advanced)。
3. 启用以管理员身份运行^(Run)选项并选择确定。

1. ^{(Select Apply)}在“属性”窗口中^(Properties)选择“应用”，然后选择“确定” 。

通过更新应用程序^(App)修复 Steam 的无连接错误^{(Connection Error)}

由于您使用的是过时的应用程序，您在 Steam 中^{(error in Steam)}收到无网络连接错误。众所周知，此类版本会导致问题，因为它们是很久以前构建的。

通过将您的应用程序更新到最新版本来解决这个问题。在Windows^(Windows)和Mac上更新Steam既快速、简单又免费。请注意，以下方法使用Steam^(Steam)中的内置选项来更新应用程序。这意味着如果Steam^(Steam)仅偶尔显示连接错误， 您可以使用此方法。

1. 在计算机上打开 Steam。
2. Select Steam > Check在应用程序菜单中选择 Steam > 检查Steam客户端更新。^{(Steam Client)}

1. 等待^(Wait)Steam找到可用的更新 。^(Steam)
2. 安装可用更新并重新启动Steam。

关闭VPN来修复 Steam 的互联网连接错误^{(Internet Connection Error)}

VPN应用程序通过第三方服务器路由您的互联网流量，这种机制可能会导致 Steam 应用程序出现^{(causing issues with the Steam app)}问题^(VPN)。在这种情况下，您可以关闭VPN服务，看看是否可以解决您的问题。

您可以通过打开应用程序并选择主屏幕上的大开/关开关来禁用大多数VPN应用程序中的服务。然后，启动Steam并查看应用程序是否连接到互联网。

关闭计算机的防火墙

如果Steam仍然无法连接到互联网，您的 Windows 或Mac防火墙可能会阻止该应用程序访问互联网。发生这种情况的原因有多种，解决此问题的一种方法是禁用防火墙^{(disable your firewall)}。

在 Windows 上

How to Fix the No Connection Error in Steam

Do you get a no connection error while using Steam on your Windows or Mac? Your game client may face issues connecting to the internet, resulting in the above error message. You can apply a few solutions to get around the problem, and we’ll show you what those solutions are.

While there are many reasons Steam can’t connect to the internet, the major ones are that your internet connection has issues, Steam is down, you’re using a VPN, and your firewall is blocking Steam’s access to the internet.

Check Your Internet Connection

Your internet connection is the first item to check when you experience a network issue. For example, your connection may be down, preventing Steam from connecting to the platform’s servers.

You can verify that by opening a web browser on your desktop and launching a site. If your site fails to load, your internet connection has an issue. In this case, follow the following basic solutions to resolve your internet problem.

Restart Your Router

Your internet router may be experiencing a minor problem, causing your internet not to work. In this case, give your router a reboot to fix many minor issues with the device.

You can restart most routers by pressing the Power button on the device. Some routers allow you to reboot from the device’s settings menu, which you can access from your computer’s web browser. In this method, you’ll select an option like Commit and Reboot to restart your router.

When your router restarts, launch Steam and see if you still get the same error.

Update Your Network Adapter Drivers

Your computer’s network adapter is how you connect to the internet. This adapter may be using outdated drivers, causing issues with your internet connection. In this case, use your Windows PC’s Device Manager utility to find and install the latest drivers for your adapter.

You don’t have to follow this process on a Mac.

1. Right-click the Start menu icon and choose Device Manager.
2. Expand Network adapters, right-click your adapter, and choose Update driver.

1. Select Search automatically for drivers.
2. Allow the tool to install the available drivers.
3. Restart your PC and launch Steam.

Check if Steam Network Is Down

Steam’s servers may be experiencing an outage, making your Steam client unable to connect to those servers. You can check if that’s the case using a few third-party sites.

You can use a site like Downdetector to check if users have reported issues using Steam. You can verify if Steam is down using the unofficial Steam Status site. Steam’s unofficial Twitter account is also a good place to check the platform’s outages.

If the platform is down, you’ll have to wait until the company fixes the issues. You can’t do anything on your end to resolve the problem.

Restart Your Windows or Mac Computer

If Steam still displays a no connection error, your Windows or Mac computer may have a minor glitch. It’s common for such minor problems to exist on these operating systems, and you can fix them by rebooting your computers.

Doing so turns off and reloads all your system features, fixing many minor issues.

On Windows

1. Open the Start menu using the Windows key.
2. Select the Power icon and choose Restart.

On macOS

1. Select the Apple logo in your Mac’s top-left corner.
2. Choose Restart in the menu.

Run Steam as Admin

Steam fails to connect to the internet because the app may not have the required permissions. This usually happens when you run the app without administrative privileges.

You can fix that by launching the app in admin mode, giving it all the rights it needs to function. This should eliminate your Steam connection error.

1. Right-click Steam’s desktop shortcut and select Run as administrator.

1. Select Yes in the User Account Control prompt.

If Steam’s no connection error is fixed after running the app as admin, make Windows always launch the app with admin rights by following the following steps:

1. Right-click Steam’s desktop shortcut and choose Properties.
2. Select the Shortcut tab and choose Advanced.
3. Enable the Run as administrator option and choose OK.

1. Select Apply followed by OK on the Properties window.

Fix Steam’s No Connection Error by Updating the App

You get a no network connection error in Steam because you’re using an outdated app. Such versions are known to cause issues as they were built long ago.

Fix that by updating your app to the latest version. It’s quick, easy, and free to update Steam on Windows and Mac. Note that the following method uses a built-in option in Steam to update the app. This means you can use this method if Steam only occasionally displays a connection error.

1. Open Steam on your computer.
2. Select Steam > Check for Steam Client Updates in the app’s menu.

1. Wait for Steam to find available updates.
2. Install the available updates and restart Steam.

Turn Off Your VPN to Fix Steam’s Internet Connection Error

A VPN app routes your internet traffic via a third-party server, and this mechanism may be causing issues with the Steam app. In this case, you can turn off your VPN service and see if that resolves your issue.

You can disable the service in most VPN apps by opening the app and selecting the large on/off toggle on the main screen. Then, launch Steam and see if the app connects to the internet.

Turn Off Your Computer’s Firewall

If Steam still fails to connect to the internet, your Windows or Mac firewall may be blocking the app’s access to the internet. This happens for various reasons, and one way to fix that is to disable your firewall.

On Windows

1. Open the Windows Security app on your PC.
2. Select Firewall & network protection in the app.
3. Choose the network that says (active).

1. Turn off the Microsoft Defender Firewall option.

1. Select Yes in the User Account Control prompt.

On macOS

1. Open a Terminal window on your Mac.
2. Type the following command in Terminal and press Enter:
   sudo defaults write /Library/Preferences/com.apple.alf globalstate -int 0
3. Type your Mac admin password and press Enter.

Make Steam Use TCP Mode for the Connection

Steam uses UDP as the default connection mode. When you experience network issues, it’s worth changing this mode to TCP to see if that resolves your issue.

On Windows

1. Right-click your Steam desktop shortcut and choose Properties.
2. Open the Shortcut tab.
3. Place your cursor at the end of the text in the Target field, press Spacebar, and type the following:
   -tcp

1. Select Apply followed by OK at the bottom.
2. Launch Steam using your desktop shortcut.

On macOS

1. Open Terminal and head to the Applications folder.
2. Type the following command in Terminal and press Enter:
   open steam.app –args -tcp
3. Steam will launch in TCP mode.

Uninstall and Reinstall Steam

If your Steam no connection error persists, your app’s core files might be corrupt. Many items, including viruses and malicious apps, can cause your app files to become unusable. In this case, you can’t fix the files, but you can uninstall and reinstall your app.

Reinstalling Steam allows you to get new working app files, which resolves any issues created by problematic files.

On Windows

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

1. Select Uninstall in the prompt to remove the app.
2. Redownload the app from Steam’s site and install the app on your PC.

On macOS

1. Open Finder and access the Applications folder.
2. Right-click your Steam app and choose Move to Trash.
3. Head to Steam’s site and download and install the app on your Mac.

Say Goodbye to Steam’s No Connection Issue

Steam is forced to display a no connection error when the app can’t connect to the internet. You can use the fixes outlined above to resolve the issue and allow Steam to connect to its servers.

Once you’ve done that, your game client’s online features will start working just as expected. Enjoy!
