有时，当您尝试访问网站时，您的浏览器会遇到“您的互联网访问被阻止”错误，并带有ERR_NETWORK_ACESS_DENIED错误代码。您可以尝试一些快速修复来重新获得 Internet 访问权限。
出于多种原因，您可能会遇到此错误。在某些情况下，它可能就像司机行为不端一样简单。但是，也可能是您的防病毒程序的防火墙阻止了对可疑网站的 Internet 访问，或者是网络管理员阻止了网站等外部因素。
在最坏的情况下，您的 PC 可能已经感染了恶意软件或病毒，这些恶意软件或病毒会改变您的网络设置，并为您提供“您的互联网访问被阻止错误”。在这种情况下，您需要使用 Windows Defender或优秀的第三方防病毒软件(good third-party antivirus software)扫描您的 PC(scan your PC using Windows Defender)。
无论您和网络之间存在什么问题，以下修复都将帮助您在接下来的几分钟内重新上线。
“关闭(Off)再打开”方法
尽管听起来很老派，但您会惊讶于重新启动 PC 可以修复多少错误。您还应该在使用时重新启动调制解调器和路由器。
如果您的调制解调器和路由器没有电源开关，请将它们从电源上拔下。让他们坐至少 60 秒。将调制解调器重新插入电源，然后再插入路由器。
如果重新启动确实解决了您的问题，您将节省几分钟的故障排除时间。如果没有，您可以尝试其他一些修复方法。
禁用您的防火墙和防病毒软件(Antivirus)
如果您的 PC 上安装了第三方防病毒程序，它可能有自己的防火墙。虽然防病毒软件不会妨碍您浏览网页，但它的防火墙可能会阻止访问它认为可能会损害您的系统的网站。禁用防火墙以查看您是否可以正常访问互联网。
所有防病毒程序的禁用防火墙的过程都不同，但您通常会在设置/首选项中的某处找到它。如果您仍然无法访问网络，请继续禁用Windows防火墙。
- 按Win + R，键入control，然后按Enter启动控制面板。
- 选择系统和安全(System and Security )> Windows Defender 防火墙(Windows Defender Firewall)。
- 从左侧窗格中选择打开或关闭 Windows Defender 防火墙。(Turn Windows Defender Firewall on or off)
- 在下一个屏幕上，为专用网络和公共网络选择关闭 Windows Defender 防火墙（不推荐） 。(Turn off Windows Defender Firewall (not recommended))
- 重新启动您的电脑。
运气好的话？如果没有，请尝试下一个修复。
重置(Reset)或重新安装您的防病毒程序(Antivirus Program)
如果您记得最近在玩弄您的防病毒程序的设置，将其设置重置为默认设置可能是个好主意。您通常会在设置中的某处找到恢复出厂设置的选项，具体取决于您使用的程序。
如果重置没有帮助，如果您有理由相信它是罪魁祸首，请重新安装您的防病毒程序。重新安装时，省略安装程序的防火墙实用程序是有意义的。拥有Windows Defender 防火墙可以提供足够的保护(Windows Defender Firewall provides enough protection)，并且在大多数情况下，您甚至可以在没有任何其他防病毒程序的情况下做得很好。
使用内置网络疑难解答(Built-in Network Troubleshooter)
Windows有一组内置的疑难解答程序，可以帮助您自动修复一系列问题。它还有一个网络疑难解答程序，您可以尝试修复“您的互联网访问被阻止”错误。网络疑难解答不擅长解决很多问题，但绝对值得一试。
- 按Win + I启动设置应用程序。
- 导航到网络和 Internet(Network & Internet ) >状态(Status )>网络疑难解答(Network troubleshooter)。
- 疑难解答程序将自动开始检测问题并尝试修复它。如果它没有发现任何问题，它会通知您。
如果故障排除找不到问题，请尝试下一个修复。
回滚驱动程序
有时，驱动程序更新可能会导致驱动程序出现故障。如果您的驱动程序最近更新并且系统保留了以前驱动程序的文件，您将能够将驱动程序回滚(roll back the driver)到以前的版本。
- 按Win + R，键入devmgmt,msc，然后按Enter启动设备管理器。
- 找到您正在使用的网络适配器。右键单击适配器并选择Properties。
- 切换到驱动程序(Driver)选项卡并选择回滚驱动程序(Roll Back Driver)。
如果该按钮显示为灰色，则表示您没有任何以前的版本可以回滚，或者以前的驱动程序的文件不再可用。在这种情况下，请尝试下一个修复。
更新或卸载驱动程序
查看(Look)制造商的网站，看看是否有更新版本的驱动程序可用。Windows大部分时间会自动更新驱动程序，但仍然值得检查更新版本。
如果您确实找到了较新的版本，请选择“回滚驱动(Roll Back Driver)程序”按钮上方的“更新驱动(Update Driver)程序”按钮。系统将询问您是否希望 Windows 搜索驱动程序或浏览计算机以查找驱动程序文件。如果您已从制造商的网站下载文件，请选择后一个选项。
如果您的驱动程序是最新的，请尝试重新安装它。返回设备管理器(Device Manager)并右键单击您的适配器。选择卸载设备(Uninstall device)。
您将看到一个提示，询问是否允许继续卸载，请选择Uninstall。
卸载后，从设备管理器(Device Manager)的顶部功能区中选择操作(Action)，然后选择扫描硬件更改(Scan for hardware changes)。这将自动重新安装您刚刚卸载的设备。
或者，您可以重新启动 PC，这也将重新安装驱动程序。
特定于浏览器的修复
您可以尝试使用浏览器进行一些操作来解决此问题。由于Chrome是最流行的浏览器，因此本节中的插图使用Chrome。但是，它在概念上仍然适用于大多数其他浏览器。
清除 Cookie 和缓存(Clear Cookies and Cache)
即使没有任何错误，每隔一段时间清除 cookie 和缓存也是一个好习惯。清除 cookie 和缓存可以消除很多浏览器问题，包括“您的互联网访问被阻止”问题。
要清除 cookie 和缓存：
- 按Ctrl + H，然后选择清除浏览数据(Clear browsing data)。
- 您现在会看到一个小窗口弹出，询问您要清除数据的时间范围。最好选择所有时间(All time)作为时间范围，并选中以下所有三个框：浏览器历史记录(Browser history)、Cookie 和其他站点数据(Cookies and other site data)以及缓存的图像和文件(Cached images and files)。完成后，选择清除数据(Clear data)。
如果这不起作用，请尝试重置浏览器。
重置铬(Reset Chrome)
如果您最近更改了任何Chrome设置，重置浏览器可能有助于解决“您的互联网访问被阻止”问题。
- 选择Chrome(Chrome)右上角的省略号，然后选择Settings。
- 从左侧窗格中选择高级(Advanced)>重置和清理。(Reset and clean up)从右窗格中，选择将设置恢复为原始默认值(Restore settings to their original defaults)。
- 当要求确认时，选择重置设置(Reset settings)。
删除 Chrome 个人资料(Delete Chrome Profile)
如果到目前为止没有任何解决方案有效，您可以尝试删除您的Chrome配置文件，看看是否会产生积极的结果。它过去曾对某些用户有用，因此它可能只对您有用。
- 按Ctrl + Shift + Esc启动任务管理器。
- 找到 Google Chrome(Find Google Chrome)，右键单击它，然后选择End task。
- 按Win + R，键入以下文本，然后按Enter：
%LOCALAPPDATA%/Google/Chrome/User Data/
- 这将带您进入用户数据(User Data )目录。查找Default文件夹并将其重命名为old.default。
- 重新启动您的电脑，看看您现在是否可以访问互联网。
禁用扩展(Disable Extensions)
作为最后的手段，如果问题确实出在浏览器中，您可以尝试禁用所有扩展程序以查看是哪个扩展程序导致了问题。
- 选择右上角的省略号。转到更多工具(More tools)>扩展程序(Extensions)。
- 您将在本节中看到浏览器上安装的所有扩展程序，每个扩展程序的右下角都有一个切换开关。一个接一个地切换它们，看看哪一个是问题所在。
你回来了吗？
希望这些修复程序之一对您有用，并且您的浏览器不再显示“您的互联网访问被阻止。” 但有时(” Sometimes)，问题可能出在您的网络上，而不是设备上。如果您的网络无法访问 Internet(network doesn’t have internet access)，您可以尝试一些特定于网络的修复程序。
Getting “Your Internet Access is Blocked”? 10 Ways to Fix
Sometimes when you try to access a website, уour browser runs into a “Your internet access is blocked” error with an ERR_NETWORK_ACESS_DENІED error code. There are a few quick fixes yoυ can try to regаin internet access.
You could encounter this error for several reasons. In some cases, it could be as simple as a driver misbehaving. However, it could also be your antivirus program’s firewall blocking internet access to suspicious websites, or an external factor such as websites being blocked by the network administrator.
In worst cases, your PC could have been infected with malware or viruses which can alter your network settings, and give you the “Your internet access is blocked error.” In this case, you’ll need to scan your PC using Windows Defender or a good third-party antivirus software.
Regardless of what stands between you and the web, the following fixes will help you get back online within the next few minutes.
The “Turn It Off and On Again” Method
As old school as it may sound, you’d be surprised by just how many errors restarting your PC can fix. You should also restart your modem and router while you’re at it.
If your modem and router don’t have a power switch, unplug them from the power source. Let them sit for at least 60 seconds. Plug the modem back into the power source, and then the router.
If a reboot does solve your problem, you’ll save yourself a couple of minutes of troubleshooting. If it doesn’t, there are a few other fixes you can try.
Disable Your Firewall and Antivirus
If you have a third-party antivirus program installed on your PC, it likely has a firewall of its own. While the antivirus doesn’t stand in the way of your browsing the web, its firewall could block access to websites that it believes could harm your system. Disable the firewall to see if you can then access the internet properly.
The process of disabling the firewall is different for all antivirus programs, but you’ll generally find it somewhere in the settings/preferences. If you still can’t access the web, go ahead and also disable the Windows firewall.
- Press Win + R, type control, and press Enter to launch the Control Panel.
- Select System and Security > Windows Defender Firewall.
- Select Turn Windows Defender Firewall on or off from the left pane.
- On the next screen, select Turn off Windows Defender Firewall (not recommended) for both private and public networks.
- Restart your PC.
Any luck? If not, try the next fix.
Reset or Reinstall Your Antivirus Program
If you remember recently playing around with your antivirus program’s settings, it’s probably a good idea to reset its settings to default. You’ll generally find a factory reset option somewhere in the settings, depending on which program you’re using.
If a reset doesn’t help, reinstall your antivirus program if you have reason to believe it’s the culprit. When reinstalling, it would make sense to leave out installing the program’s firewall utility. Having Windows Defender Firewall provides enough protection, and in most cases, you’d even do just fine without any other antivirus program.
Use the Built-in Network Troubleshooter
Windows has a set of built-in troubleshooters that can help you automatically fix a range of problems. It also has a network troubleshooter that you can try to fix the “Your internet access is blocked” error. The network troubleshooter isn’t great at fixing a lot of issues, but it’s definitely worth a shot.
- Press Win + I to launch the Settings app.
- Navigate to Network & Internet > Status > Network troubleshooter.
- The troubleshooter will automatically begin to detect the problem and try to fix it. If it doesn’t find any issues, it will let you know.
If the troubleshoot couldn’t find the problem, try the next fix.
Roll Back Driver
Sometimes a driver update can cause the driver to malfunction. If your driver was recently updated and the system had retained the files for the previous driver, you’ll be able to roll back the driver to the previous version.
- Press Win + R, type devmgmt,msc, and press Enter to launch the Device Manager.
- Find the network adapter you’re using. Right-click on the adapter and select Properties.
- Switch to the Driver tab and select Roll Back Driver.
If the button is greyed out, it means you didn’t have any previous versions to roll back to, or the files for the previous driver are no longer available. In that case, try the next fix.
Update or Uninstall the Driver
Look through the manufacturer’s website to see if there’s a newer version of your driver available. Windows automatically updates drivers most of the time, but it’s worth checking for a newer version nonetheless.
If you do find a newer version, select the Update Driver button just above the Roll Back Driver button. You’ll be asked if you want Windows to search for a driver or browse through your computer for driver files. Select the latter option if you’ve downloaded the files from the manufacturer’s website.
If your driver is up-to-date, try reinstalling it. Go back to the Device Manager and right-click on your adapter. Select Uninstall device.
You’ll see a prompt asking permission to continue uninstallation, select Uninstall.
Once it’s uninstalled, select Action from the top ribbon in the Device Manager and select Scan for hardware changes. This will automatically reinstall the device you just uninstalled.
Alternatively, you could restart your PC and that will reinstall the driver as well.
Browser-Specific Fixes
There are a few things you can try with your browser to fix this issue. Since Chrome is the most popular browser, the illustrations in this section use Chrome. However, it’s still conceptually applicable to most other browsers.
Clear Cookies and Cache
It’s good practice to clear cookies and cache every once in a while even without any errors. Clearing cookies and cache can eliminate a lot of browser problems, including the “Your internet access is blocked” issue.
To clear cookies and cache:
- Press Ctrl + H, and select Clear browsing data.
- You’ll now see a small window pop up asking you about a time range for which you want to clear the data. It’s best to select All time as the time range and check all three boxes below: Browser history, Cookies and other site data, and Cached images and files. When you’re done, select Clear data.
If this doesn’t work, try resetting the browser.
Reset Chrome
If you’ve changed any Chrome settings recently, resetting the browser may help address the “Your internet access is blocked” issue.
- Select the ellipsis at the top-right corner of Chrome and select Settings.
- Select Advanced > Reset and clean up from the left pane. From the right pane, select Restore settings to their original defaults.
- When asked for confirmation, select Reset settings.
Delete Chrome Profile
If none of the solutions so far worked, you could try deleting your Chrome profile and see if that yields positive results. It has worked for some users in the past, so it might just work for you.
- Press Ctrl + Shift + Esc to launch the Task Manager.
- Find Google Chrome, right-click on it, and select End task.
- Press Win + R, type the following text, and then press Enter:
%LOCALAPPDATA%/Google/Chrome/User Data/
- This will take you to the User Data directory. Look for the Default folder and rename it to old.default.
- Restart your PC and see if you can access the internet now.
Disable Extensions
As a last resort, if the problem is indeed within the browser, you could try disabling all extensions to see which one is causing the issue.
- Select the ellipsis at the top-right corner. Go to More tools > Extensions.
- You’ll see all the extensions installed on your browser in this section with a toggle switch at each extension’s bottom-right corner. Toggle them off one-by-one to see which of these was the problem.
Are You Back Online?
Hopefully, one of these fixes worked for you and your browser no longer says “Your internet access is blocked.” Sometimes, though, the issue could be with your network and not the device. If your network doesn’t have internet access, you could try a few network-specific fixes.
