visual-studio - 在 Manage Extensions, VS 2019 中强行关闭现有连接

Question

刚刚在新的笔记本电脑上安装了 vs2019 社区。
打算安装一些扩展，我看到了这个

如果我刷新几次，我可能会看到扩展，但在下一次刷新或进入扩展的下一页时，我看到了同样的事情。
不知道发生了什么，为什么以及如何解决它。
更新
我试图从 marketplace 安装扩展地点。它失败了

我再次打开日志，同样的错误:

更新 2
似乎即使从浏览器连接到市场也是一个问题

更新 3
使用 Fiddler 进一步检查问题后，我发现 HTTPS 握手失败。
更新 4
通过另一个WIFI网络连接到互联网时，问题消失了。更具体地说，我将我的手机变成了 wifi 热点并通过手机连接。不再有与 Visual Studio 市场的连接错误...
更新 5 - 解决方案
在我意识到问题出现在某些 wifi 网络中而不是总是出现后，我怀疑我的 wifi 适配器设置有问题。我从我的适配器设置中删除了 ipv6，一切都像魅力一样。

Answer 1

在阅读了该问题的许多不同解决方案后，其中大部分是关于代理设置的配置，我终于找到了导致我遇到问题的原因。
我发现的所有解决方案都没有奏效。唯一足够接近的是一篇关于从 Visual Studio 的配置文件中禁用 ipv6 的帖子。我做到了，但似乎忽略了更改。所以我虽然ipv6不会是我的案例的根本原因并改变了方向，但徒劳无功。
当我在某个时候需要连接到不同的 Wi-Fi 网络时，我意识到问题已经解决了。只有在某些 wi-fi 中我遇到了这个问题，而且只有在我的笔记本电脑上。不是我的任何其他设备。所以我怀疑一定是我的笔记本电脑的 Wi-Fi 适配器设置和 Wi-Fi 网络的某种组合导致了问题。
摆弄我的 Wi-Fi 网络适配器的设置，我找到了我需要做的事情。 我不得不从我的 Wi-Fi 适配器设置中禁用 ipv6 .
问题消失了。
