问 VisualStudio2019- IIS连接被重置(ERR_CONNECTION_RESET)

EN

我在VisualStudio2019中创建了一个新的HTTPS启用选项ASP.NET Core项目。当我用IIS运行这个项目时，网页上写着' The Connection I ‘。

当我第一次为项目启用SSL并以调试模式启动时，visual studio提示我信任自签名证书，然后单击“是”。但是，在浏览器中，站点没有打开，并且显示了“连接被重置”的错误。

应用程序运行在端口44300上。

这是Windows 10和Visual 2019的新安装。

我验证了IIS生成的自签名证书是否存在于证书存储区中(参见屏幕快照)。此外，证书也存在于边缘浏览器和Google浏览器的受信任根证书颁发机构中。

​

​

• 我创建了一个新项目，以确保我的配置或构建文件中没有任何错误。当我运行这个新项目时，我得到了相同的结果。

• 我也尝试过其他浏览器，但仍然是相同的错误.

• --我使用Visual安装程序修复了Visual，并将一切重置为默认，但没有成功。

请就如何解决这一问题提出建议。
