【问题描述】：
我的从 Visual Studio 2017 到我的 Azure Web 应用程序的 Web 部署发布昨天很挑剔，今天完全停止工作。
昨天事件查看器中的错误是
Error Code: 6 Exception Message: Could not connect to the remote computer ("MYDOMAIN.scm.azurewebsites.net") using the specified process ("Web Management Service") because the server did not respond.

今天的错误是：

在查看了许多关于此事的不确定帖子后，（由于此错误 ERROR_CONNECTION_TERMINATED 未列在他们在错误中提供的官方故障排除网站上），我做了以下事情： (1) 重启我的电脑 （2）重启Visual Studio (3) 以管理员身份打开 Visual Studio (4) 从 Azure 重新下载发布配置文件
这些都不起作用。
在发布配置文件窗口中，当我为我的凭据单击“验证”时，它们通过了。只有当我预览或运行发布时才会出错。
最终奏效的是
(5) 在 Azure WEBSITE_WEBDEPLOY_USE_SCM 中将应用程序设置设置为 false
我查看了它，但不确定它做了什么，为什么我需要这样做，以及为什么在没有此设置之前它可以正常工作。感觉就像一个黑客修复，我不喜欢它。我应该保留此应用程序设置吗？
更新： 不确定 SCM 设置是否有帮助。我可以发布一次，以后不能再发布了。
【问题讨论】：
-
如果问题出在 Azure 端，您是否尝试重新创建应用服务？
-
@CarlosGarcia 重新创建应用服务是什么意思？

出现这个问题的原因很多，请确保您的部署工具没有问题。
