Bug description

You should be able to access to a directory shared with a link in webdav according to this page: https://docs.nextcloud.com/server/latest/user_manual/en/files/access_webdav.html#accessing-public-shares-over-webdav

However, when trying to do so on windows 10, windows refuse the URL witht the message "The folder you entered does not appear to be valid. Please choose another".

Please note that:

• Accessing to the account wide webdav (XXX/remote.php/dav/files/XXX/) does work without issue on windows 10
• Accessing to the shared link webdav does work when trying with http (even if NC tell you that it's useless to access to webdav in http) and with an other tool (rclone)

Steps to reproduce

1. Create a folder and add some file in it
2. Share this folder with a sharing link and get the share token
3. On windows 10, open file explorer and right click on "This PC" then choose "Add a network location".
4. Paste this url : https://NEXTCLOUD_URL/public.php/webdav
5. Press the next button

Expected behavior

Windows should ask you for creditential to connect to the webdav url (and it should then work by using the share token as user and no password).
