如果您无法打开任何网站，而是在Google Chrome中收到^{(Google Chrome)}ERR QUIC PROTOCOL ERROR 错误消息，这里有一些可能对您有用的解决方案。错误消息如下所示：

This site can’t be reached, The webpage at [website URL] might be temporarily down or it may have moved permanently to a new web address, ERR_QUIC_PROTOCOL_ERROR

当URL关闭时，您会看到此消息 - 但如果您知道该站点未关闭但仍然看到此消息，您可能需要进一步排除故障。

ERR_QUIC_PROTOCOL_ERROR

1]禁用QUIC协议

根据 Wikipedia 的说法，QUIC是一种实验性的传输层网络协议，它存在于Google Chrome中，用于通过UDP在两个端点之间建立连接。如果开发方面出现问题，在Google Chrome中打开任何网站时都有可能收到此错误消息。因此，您可以在浏览器中禁用此实验性协议并检查问题是否仍然存在。

打开谷歌浏览器^{(Google Chrome)}并在地址栏中输入：

chrome://flags/

接下来，搜索Experimental QUIC 协议。^{(Experimental QUIC protocol.)}

默认情况下，它应该设置为Default。展开下拉菜单并选择禁用^(Disable)。现在，您需要重新启动浏览器。

2]登录您的 ISP 帐户时Disable VPN/Proxy

有一些ISP^(ISPs)使用特定方法来区分用户帐户。出于安全目的，它们在用户实际使用互联网之前包含登录提示。在这种情况下，您需要拥有用户名和密码才能登录您的 ISP 提供的用户帐户。如果你有这个，你需要先登录。

一个简单的解决方法是在登录您的用户帐户时禁用您的VPN或代理。^(Proxy)如果您是第一次使用ISP并且您没有用户名或密码，您可以询问您的ISP是否有这样的协议。

希望建议有所帮助。^{(Hope the suggestions help.)}

Fix ERR_QUIC_PROTOCOL_ERROR in Google Chrome

If you are not able to open any website but instead you receive ERR QUIC PROTOCOL ERROR error message in Google Chrome, here are some solutions that might be useful for you. The error message looks like this:

This site can’t be reached, The webpage at [website URL] might be temporarily down or it may have moved permanently to a new web address, ERR_QUIC_PROTOCOL_ERROR

You see this message when the URL is down – but if you know that the site is not down but still see this message, you may need to troubleshoot further.

ERR_QUIC_PROTOCOL_ERROR

1] Disable QUIC Protocol

According to Wikipedia, QUIC is an experimental transport layer network protocol that is present in Google Chrome to make a connection between two endpoints over UDP. If there is a problem on the development side, there is a chance of getting this error message while opening any website in Google Chrome. Therefore, you can disable this experimental protocol in your browser and check whether the problem remains or not.

Open Google Chrome and enter this in the address bar:

chrome://flags/

Next, search for Experimental QUIC protocol.

By default, it should be set to Default. Expand the drop-down menu and select Disable. Now, you need to restart the browser.

2] Disable VPN/Proxy when logging into your ISP’s account

There are some ISPs that use a particular method to differentiate user accounts. For security purposes, they include a login prompt before the user can actually use the internet. In that case, you need to have a username and password to log into your ISP-provided user account. If you have that, you need to log in first.

A simple workaround would be to disable your VPN or Proxy while logging into your user account. If you are using an ISP for the first time and you do not have a username or password, you can ask your ISP if they have such a protocol or not.

Hope the suggestions help.
