在网络上，您会看到两种不同类型的URL^(URLs)或链接——一种以HTTP开头，另一种以HTTPS开头。HTTPS链接使用SSL证书^(SSL)使连接安全或私密。有时，用户报告说，当他们使用任何 Web 浏览器时， HTTPS 站点都无法打开。^{(HTTPS sites are not opening)}例如，Google Chrome的用户可能会看到他们的浏览器显示Your connection is not private、NET::ERR_CERT_AUTHORITY_INVALID错误页面。

NET::ERR_CERT_AUTHORITY_INVALID

如果您无法使用Google Chrome、Internet Explorer、Firefox或^(Firefox)Windows PC上的任何浏览器打开任何HTTPS网页，您可以尝试以下方法。

HTTPS网站无法在任何浏览器中打开

除非或直到您确保问题属于您而非网站所有者，否则您不应采取任何进一步的行动。为此，您需要在永久链接中打开多个具有HTTPS的网站。如果所有HTTPS站点都没有在您的常规浏览器中打开 - 但它们在其他 Web 浏览器中打开，这意味着您需要解决您的问题。

1]更改时间

如果您无法打开HTTPS网站，这是最常见的修复方法。通过更改日期和时间，您可以在瞬间解决此问题。要更改Windows 10中的日期和时间，请按Win + I 按钮打开设置面板。^(Settings)选择时间和语言^{(Time & language )}>日期和时间^{(Date & time)}。接下来，单击时区^{(Time zone )}下拉菜单，然后选择与所选时区不同的时区。现在，尝试打开任何显示错误的HTTPS站点。^(HTTPS)

2]清除SSL缓存

虽然这不应该是一个问题，但有时这会产生问题。您需要清除SSL缓存。您可以从Internet 选项^{(Internet Options)}页面 >内容^{(Content )}选项卡执行此操作。在该页面上，您会找到一个名为Clear SSL state的选项。点击它。

3]验证SSL证书

如果您已尝试上述建议，但问题仍然存在，您可能需要测试SSL证书。为此，请访问此网站^{(this website)}，然后输入显示隐私错误^{(Privacy Error)}的网站的整个URL。如果它显示所有绿色勾号，则表明该站点的SSL证书很好，只有您遇到了问题。但是，如果您发现任何红叉，则意味着您无法解决该问题，站点管理员需要采取措施。

4]刷新DNS缓存

打开命令提示符^{(Command Prompt)}窗口并运行以下命令以刷新 DNS 缓存^{(flush the DNS cache)}：

ipconfig /flushdns

这有帮助吗？

5]禁用VPN

我安装了ProtonVPN，它似乎是一个可靠的Windows VPN 软件^{(VPN software)}。但是我在安装VPN^(VPN)后开始收到这个问题。因此，如果您使用的是VPN软件，请禁用它并查看它是否有帮助。

6]重置或重新安装浏览器

如果您已经开始在Google Chrome中收到此^{(Google Chrome)}隐私错误^{(Privacy Error)}消息，您可以先尝试重置浏览器。以下是一些可能对您有所帮助的链接 –重置 Chrome 浏览器^{(Reset Chrome browser)}| 重置 Internet Explorer | 重置火狐| 重置边缘^{(Reset Edge)}。如果这不能解决问题，您可能需要重新安装浏览器。

希望^(Hope)这里的东西可以帮助您解决问题。

HTTPS sites not opening in any browser on Windows computer

On the web, you will ѕее two different types of URLs or linkѕ – one which starts with HTTP and the other which starts with HTTPS. The HTTPS links use SSL certificates to make the connection secure or private. At times, users have reрorted that HTTPS sites are not opening when they use any web browser. For instance, users of Google Chrome may see their browser display Your connection is not private, NET::ERR_CERT_AUTHORITY_INVALID error page.

NET::ERR_CERT_AUTHORITY_INVALID

If you are unable to open any HTTPS web page using Google Chrome, Internet Explorer, Firefox or any browser on your Windows PC, here are a few things you could try.

HTTPS sites not opening in any browser

You should not take any further action unless or until you ensure that the problem belongs to you and not the site owner. For that, you need to open multiple websites having HTTPS in the permalink. If all the HTTPS sites are not opening in your regular browser – but they are opening in other web browsers, that means you need to solve your problem.

1] Change time

This is the most common fix if you are unable to open HTTPS websites. By changing the date and time, you can fix this issue within moments. To change the date and time in Windows 10, open Settings panel by pressing Win + I button. Select Time & language > Date & time. Next, click the Time zone drop-down menu, and select a different time zone other than the selected one. Now, try to open any HTTPS site that was showing an error.

2] Clear SSL cache

Although it should not be an issue, sometimes this can create problems. You need to clear the SSL cache. You can do that from Internet Options page > Content tab. On that page, you will find an option called Clear SSL state. Click on it.

3] Verify SSL certificates

If you have tried the above suggestions, but the problem is still there, you may need to test the SSL certificate. To do this, head over to this website, and enter the whole URL of the site which displays the Privacy Error. If it displays all green ticks, that implies the site’s SSL certificate is fine, and only you are getting the problem. However, if you find any red crosses, it means you cannot fix that problem, and the site admin needs to take action.

4] Flush DNS Cache

Open a Command Prompt window and run the following command to flush the DNS cache:

ipconfig /flushdns

Does this help?

5] Disable VPN

I installed ProtonVPN, which seems to be a reliable VPN software for Windows. But I started receiving this issue after installing the VPN. So if you are using VPN software, disable it and see if it helps.

6] Reset or Reinstall the browser

If you have started getting this Privacy Error message in Google Chrome, you can try to reset the browser first. Here are some links that may help you – Reset Chrome browser | Reset Internet Explorer | Reset Firefox | Reset Edge. If that doesn’t solve the issue, you may need to reinstall the browser.

Hope something here help you in resolving the problem.
