即使成功注册，也无法浏览到托管在 IIS Express 中的站点

如何解决即使成功注册，也无法浏览到托管在 IIS Express 中的站点

我正在尝试在 IIS Express 中运行 ASP.NET Core MVC 应用程序（100% 模板）。该站点似乎已托管在 IIS Express 中，但是当我在浏览器中打开该站点时，出现一般错误“无法访问此站点”。有什么想法吗？

来自 Visual Studio：

Starting IIS Express ...
Successfully registered URL "http://localhost:55516/" for site "WebApplication1" application "/"
Successfully registered URL "https://localhost:44331/" for site "WebApplication1" application "/"
Registration completed for site "WebApplication1"
IIS Express is running.
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Development

看看 DevTool，这是我得到的回应：

我的launchSettings.json：

{
  "iisSettings": {
    "windowsAuthentication": true,"anonymousAuthentication": false,"iisExpress": {
      "applicationUrl": "http://localhost:55516","sslPort": 44331
    }
  },"profiles": {
    "IIS Express": {
      "commandName": "IISExpress","launchbrowser": true,"environmentvariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },"WebApplication1": {
      "commandName": "Project","applicationUrl": "https://localhost:5001;http://localhost:5000","environmentvariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

编辑：有趣的是，如果我从 VS F5 就不会运行。如果我从 CLI 运行“dotnet run”，它运行得非常好......为什么？？？
