Update Windows solution and alternate connection address.
Based on multiple error trying to connect to multiple Nextcloud 16 servers thought WebDav, the correct address to get access from File Explorer or CLI is \domain.comSSL\DavWWWRoot\remote.php\dav\files\username or if a subdomain is present (has in the current manual example) \domain.comSSL\DavWWWRoot\subdomain\remote.php\dav\files\username. Also add another solution to WebDav connection problems based on the "WebClient" service from Windows not beign started.
A part of the problem it's described in this next Nextcloud forum topic: https://help.nextcloud.com/t/webdav-problems-in-windows-7-8-10
Wow, how weird is that! https://superuser.com/questions/494203/how-to-access-webdav-using-windows-explorer-on-windows-7
Interesting. Is this working properly, meaning is the connection stable an fast? Currently in the forums, we rather recommend to use 3rd party software and it would be cool to have a native implementation that works well. And which windows versions are working with that solution (if it works for one environment, we can ask the community to help with other versions)?
