无法直接将NCdownloader的下载目录设置为Webdav地址

[EITSxiaozhai]

Describe the bug
我使用了Alist链接了天翼云盘，将Alist的webdav挂载到nextcloud，随后，将Ncdownloader的下载地址设置为Nextcloud的webdav目录，随后，当我再点击到ncdownload界面后，出现了错误。

To Reproduce
Steps to reproduce the behavior:
1.使用AList挂载天翼云盘。
2.使用nextcloud的外部存储功能挂载Alist的webdav
3.挂载完成后，点击回到Ncdownloader下载界面，出现了错误

Expected behavior
无法使用Ncdownloader功能，当把下载地址设置回本地目录时，ncwonloader功能可用

这个会不会和Nextcloud本身有关，AList的webdav不存在页面。只有一个用户名密码验证
