Npm HTTP 502错误仅适用于Azure Devops中的cordova插件包

我们在Azure Devops中有一个专用npm源，它与npm公共注册表源上游连接。

突然，这意味着从今天开始，在没有明显改变项目依赖项和提要配置的情况下，当我们执行指向项目的.npmrc（一如既往）或构建管道中的提要的npm安装时，会给我们一个HTTP 502错误，但仅适用于与cordova插件相关的包：

这很奇怪，但对于那些cordova插件的包来说只是失败了，而且该项目还有更多的依赖项，这些依赖项正在得到解决（HTTP 200/304用于缓存依赖项）

与该问题有关的连接到cordova插件的npm模块示例如下：

"cordova-plugin-advanced-http": "1.11.1",
    "cordova-plugin-app-version": "0.1.9",
    "cordova-plugin-background-mode": "0.7.1",
    "cordova-plugin-badge": "0.8.7",
    "cordova-plugin-camera": "4.0.3",
    "cordova-plugin-compat": "1.2.0",
    "cordova-plugin-device": "2.0.2",
    "cordova-plugin-file": "6.0.1",
    "cordova-plugin-file-opener2": "2.0.19",
    "cordova-plugin-geolocation": "4.0.1",
    "cordova-plugin-hockeyapp": "5.1.2",
    "cordova-plugin-ionic-webview": "1.2.1",
    "cordova-plugin-network-information": "2.0.1",
    "cordova-plugin-splashscreen": "5.0.2",
    "cordova-plugin-statusbar": "2.4.2",
    "cordova-plugin-whitelist": "1.3.3",
    "cordova-sqlite-storage": "2.3.2",

如果我们直接指向npm公共注册表（不通过私有提要），一切正常，没有HTTP 502错误，npm安装过程完成正常，因此似乎只有在通过私有提要安装依赖项时才会发生

看起来Azure DevOps和NPM public registry之间存在通信问题，但..仅适用于Cordova插件模块？奇怪的事。。。最近有人遇到过这种奇怪的问题吗？谢谢。

与Microsoft联系后，问题已得到解决。我不知道是手动还是自动（无需干预）解决了问题，但我们经历了大约7个小时的问题。在联系Microsoft后，问题得到了解决。我不知道是手动还是自动（无需干预）解决了问题，但我们经历了大约7个小时的问题。
