谷歌浏览器^{(Google Chrome)}可以通过尝试获取代理脚本来减慢您的网络浏览速度，即使它没有必要。我们将向您展示如何在Windows和Mac上修复 Chrome 的“下载代理脚本”问题。

每当您访问特定网站或在网络之间切换时，您是否会在Google Chrome状态栏上看到“正在下载代理脚本”消息？通常，它只会弹出几秒钟，然后一切都开始快速运行。但有时，它会停留更长时间，导致烦人的延迟或完全停止加载网页。

继续阅读以了解为什么在您的 PC 或Mac上使用^(Mac)Chrome浏览器时会出现“正在下载代理脚本”消息，以及您可以采取哪些措施使其消失。

为什么您会看到 Chrome 的“下载代理脚本”消息

当浏览器尝试从本地网络查找或下载自动代理配置脚本（或PAC ）时，Chrome 的“正在下载代理脚本”消息会出现。^(PAC)PAC包含允许浏览器使用代理服务器作为您的计算机和 Internet 服务提供商之间的中介^{(use a proxy server as an intermediary)}的指令。

代理在工作或学校环境中提供各种好处。例如，它们可以压缩数据以节省带宽、缓存文件以加快浏览速度、远程过滤广告等。但是，让浏览器在专用网络上寻找代理服务器可能会导致不必要的延迟。

如果您看到 Chrome 卡在“下载代理脚本”，您可以通过禁用Windows和 macOS 中的自动代理检测来解决此问题。如果在其他浏览器（例如Microsoft Edge^{(Microsoft Edge)}、Apple Safari和Mozilla Firefox ）中出现问题，以下说明也会有所帮助。

修复^{(Fix Downloading Proxy Script Error)}在Windows上下载代理脚本错误^(Windows)

如果Chrome下载代理脚本的时间过长或被卡住，您必须默认阻止它搜索代理。由于浏览器根据系统网络设置工作，因此请使用Windows 11/10 设置^(Settings)应用程序或Internet 选项^(Options)对话框中的代理管理窗格来关闭自动代理检测。

通过设置应用^{(Settings App)}禁用代理设置^{(Proxy Settings)}

Windows 10/11“设置”^(Settings)应用访问或停用您的代理设置：

1. 打开开始菜单^{(Start menu )}并选择设置^(Settings)。

2. 选择标有网络和互联网^{( Network & internet)}的类别。

3. 向下滚动并选择代理^(Proxy)。

4. 关闭自动检测设置^{(Automatically detect settings)}旁边的开关。此外，禁用使用安装脚本^{(Use a setup script)}和使用代理服务器^{(Use a proxy server)}（如果处于活动状态）。

5. 退出设置应用程序。

或者，您可以通过Chrome 设置^{(Chrome Settings)}页面进入第4步中的屏幕。⁽⁴⁾只需^(Just)打开Chrome 菜单^{( Chrome menu)}（选择地址栏右侧带有三个点的图标），然后选择Settings。然后，选择侧栏上的高级^{(Advanced )}>系统。^{(System )}接下来，选择Open your computer's proxy settings。

通过Internet选项禁用代理设置^{(Proxy Settings)}

如果您trouble loading the Windows 10/11 Settings或在 PC 上使用旧版本的Windows，您可以使用Internet 属性^(Properties)阻止Chrome搜索代理。要做到这一点：

1. 打开开始菜单^{(Start menu)}，键入Internet 选项^{( Internet Options)}，然后按Enter。

2. 切换到连接^{(Connections )}选项卡。

3. 选择局域网(LAN) 设置下的^{(Local Area Network (LAN) settings)}LAN 设置^{(LAN settings)}按钮。

4. 清除自动检测设置^{(Automatically detect settings)}旁边的复选框。此外，取消选中使用自动配置脚本^{(Use automatic configuration script )}和为 LAN 使用代理服务器^{(Use a proxy server for your LAN )}复选框（如果处于活动状态）。

5. 选择确定^(OK)。

修复^{(Fix Chrome Downloading Proxy Script Issue)}Mac上的Chrome 下载代理脚本问题

假设在Mac上使用^(Mac)Google Chrome网络浏览器出现“下载代理脚本”问题。就像在 PC 上一样，您必须在 macOS 的网络设置中停用自动代理检测才能解决问题。要做到这一点：

1. 打开Apple 菜单^{(Apple menu)}并选择系统偏好设置^{(System Preferences)}。

2. 选择窗口左下方的网络类别。^(Network)

3.在左侧窗格中选择您的互联网连接（Wi-Fi或以太网） 。^{(Ethernet) )}

4. 选择高级^(Advanced)按钮。

5. 切换到代理^(Proxies)选项卡。

6. 取消选中Auto Proxy Discovery^{(Auto Proxy Discovery)}旁边的复选框。此外，禁用自动代理配置^{(Automatic Proxy Configuration)}和任何其他协议（如果处于活动状态）。

7. 选择确定^(OK)。

您还可以在第 5 步中通过Chrome访问您 Mac 的代理设置。只需^(Just)打开Chrome 菜单^{( Chrome menu)}并选择Settings > Advanced Settings > System > Open your computer's proxy settings。

你还能做什么？

在Windows^(Windows)和Mac上对 Chrome 的“下载代理脚本”错误进行故障排除就像禁用代理设置一样简单。但是，您很少需要跟进以下修复：

• 重新启动计算机和路由器。
• 重置路由器^{(Reset router)}。
• 刷新 DNS 缓存^{(Flush the DNS cache)}。
• 运行反恶意软件扫描^{(Run an anti-malware scan)}。
• 识别并删除^{(remove )}冲突的^{(conflicting)}浏览器扩展^{( browser extensions)}。
• 重置计算机的网络设置^{(Reset your computer’s network settings)}。

如果这发生在组织网络上，请联系您的系统管理员以获取代理脚本地址或正确的手动代理设置详细信息。

How to Fix Chrome “Downloading Proxy Script” Message

Google Chrome can slow down your web browsing by attempting to fetch proxy scripts even when it doesn’t have to. We will show you how to fix Chrome’s “Downloadіng Proxy Script” іssue on Windows and Mac.

Do you see the message “Downloading Proxy Script” on the Google Chrome status bar whenever you visit specific sites or switch between networks? Usually, it pops just for a couple of seconds, and everything starts working quickly. But sometimes, it stays around for longer, causing annoying delays or stopping web pages from loading altogether.

Read on to learn why the “Downloading Proxy Script” message shows up while using the Chrome browser on your PC or Mac and what you can do to make it disappear.

Why You See Chrome’s “Downloading Proxy Script” Message

Chrome’s “Downloading Proxy Script” message appears when the browser attempts to locate or download an automatic proxy configuration script (or PAC) from the local network. A PAC consists of instructions that allow the browser to use a proxy server as an intermediary between your computer and the internet service provider.

Proxies provide various benefits in a work or school setting. For example, they can compress data to conserve bandwidth, cache files to speed up browsing, filter advertisements remotely, etc. However, having the browser looking for proxy servers on private networks can result in unnecessary delays.

If you see Chrome getting stuck at “Downloading Proxy Script,” you can fix that by disabling automatic proxy detection in Windows and macOS. The following instructions will also help if the issue occurs in other browsers such as Microsoft Edge, Apple Safari, and Mozilla Firefox.

Fix Downloading Proxy Script Error on Windows

If Chrome takes too long to download a proxy script or gets stuck doing that, you must stop it from searching for proxies by default. Since the browser works as per the system network settings, use the proxy management pane in the Windows 11/10 Settings app or the Internet Options dialog to turn off automatic proxy detection.

Disable Proxy Settings via Settings App

To access or deactivate your proxy settings via the Settings app in Windows 10/11:

1. Open the Start menu and select Settings.

2. Select the category labeled Network & internet.

3. Scroll down and select Proxy.

4. Turn off the switch next to Automatically detect settings. Additionally, disable Use a setup script and Use a proxy server if active.

5. Exit the Settings app.

Alternatively, you can get to the screen in step 4 via the Chrome Settings page. Just open the Chrome menu (select the icon with three dots to the right of the address bar) and choose Settings. Then, select Advanced > System on the sidebar. Next, choose Open your computer’s proxy settings.

Disable Proxy Settings via Internet Options

If you have trouble loading the Windows 10/11 Settings or use an older version of Windows on your PC, you can use Internet Properties to stop Chrome from searching for proxies. To do that:

1. Open the Start menu, type Internet Options, and press Enter.

2. Switch to the Connections tab.

3. Select the LAN settings button under Local Area Network (LAN) settings.

4. Clear the checkbox next to Automatically detect settings. Also, uncheck the Use automatic configuration script and Use a proxy server for your LAN boxes if active.

5. Select OK.

Fix Chrome Downloading Proxy Script Issue on Mac

Suppose the “Downloading Proxy Script” issue occurs using the Google Chrome web browser on a Mac. Like on a PC, you must deactivate automatic proxy detection within macOS’s network settings to resolve the issue. To do that:

1. Open the Apple menu and select System Preferences.

2. Select the Network category at the bottom left of the window.

3. Select your internet connection (Wi-Fi or Ethernet) on the left pane.

4. Select the Advanced button.

5. Switch to the Proxies tab.

6. Uncheck the box next to Auto Proxy Discovery. Also, disable Automatic Proxy Configuration and any other protocols if active.

7. Select OK.

You can also get to your Mac’s proxy settings in step 5 via Chrome. Just open the Chrome menu and select Settings > Advanced Settings > System > Open your computer’s proxy settings.

What Else Can You Do?

Troubleshooting Chrome’s “Downloading Proxy Script” error on Windows and Mac can be as easy as disabling your proxy settings. Rarely, however, you might want to follow up with the following fixes:

• Restart your computer and router.
• Reset router.
• Flush the DNS cache.
• Run an anti-malware scan.
• Identify and remove conflicting browser extensions.
• Reset your computer’s network settings.

If this occurs on an organizational network, contact your systems administrator for a proxy script address or the correct manual proxy setup details.
