@doskabouter, refreshing the sites pulled in your updated OnlineVideos.Sites.doskabouter.dll, which now is able to browse the folders. Also folders with spaces in them are no problem for browsing but playing a file does not work as the spaces in the path are not handled correctly. This applies...
I am trying to use the WebDAV feature with my Nextcloud. However, there is an issue in how OnlineVideos assembles the request for subfolders:
# base path configured: https://mynextcloudhost.com/remote.php/dav/files/media
# initial request to list top level folder --> OK
xxx.xxx.xxx.xxx...
