今天我在WSO2 EMM中遇到了问题。 首先，我已将Windows Phone降级为Windows 8.1。
我输入了用户admin@carbon.super和密码。然后我被重定向到之前的页面（手动输入发现服务器地址 - ＆gt; https://docs.wso2.com/display/EMM220/Registering+a+Windows+Device+Using+the+QR+Code?preview=/53124696/53286462/Windows_auto_discovery_fails.png）
Stdout日志告诉我：

我做错了什么？
WSO2MDM_VERSION 2.2.0， 来自ubuntu：16.04（Docker）
有什么想法吗？
问候！
