谷歌云平台上的NET Core 2.1无法验证HTTPS连接TLS握手失败，数据包格式意外

Question

我正试图在谷歌云平台中设置我的web应用程序并使用https。当浏览器尝试通过https端口连接时，Kestrel报告如下：

Hosting environment: Development
Content root path: /home/cvanem2/abc/HelloWorldAspNetCore
Now listening on: https://localhost:5001
Now listening on: http://localhost:5000
Application started. Press Ctrl+C to shut down.
dbug: HttpsConnectionAdapter[1]
Failed to authenticate HTTPS connection.
System.IO.IOException: The handshake failed due to an unexpected packet format.

--- End of stack trace from previous location where exception was thrown ---

--- End of stack trace from previous location where exception was thrown ---
at Microsoft.AspNetCore.Server.Kestrel.Https.Internal.HttpsConnectionAdapter.InnerOnConnectionAsync(ConnectionAdapterContext context)ext)

我的生产代码有这个问题，但使用提供的示例代码也可以很容易地生成它。如果你有一个谷歌云平台项目设置，以下是如何重现问题的说明：

1. 打开GCP终端窗口
2. sudo apt-get-y安装dotnet-sdk-2.1
3. dotnet新剃须刀-o HelloWorldAspNetCore
4. cd HelloWorldAspNetCore/
5. dotnet开发证书https
6. dotnet运行
7. 将"Web预览"设置为"端口5001"，然后尝试打开。错误将显示在终端窗口中

同样的代码在Windows PC上运行良好。我还将Windows代码编译到Windows上的linux docker容器中，并执行了docker。如果代码在docker中执行，则会出现此问题，因此它似乎与运行.net代码的操作系统有关。我试图用Wireshark分析Docker映像中的TLS数据包，但在最初的几个数据包之后，数据被加密了，没有任何错误。如有任何帮助，我们将不胜感激。

您可以更改launchSettings.json，在https 之前修改http

"WebApplication2": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "api/values",
"environmentVariables": {      
"ASPNETCORE_ENVIRONMENT": "Development"
},
**"applicationUrl": "http://localhost:5000;https://localhost:5001"**
}
