issues might be that we are using the wrong port https://github.com/owncloud/ocis-thumbnails/issues/29 & that the previews require, but should not the etag https://github.com/owncloud/ocis-thumbnails/issues/28

Currently thumbnail service doesn't work with basic auth. So, we cannot get preview using 9200 and using 9140 gives the actual file instead of preview as the thumbnail service and the rest of the webdav service are still separated in two services and until they are merge we can't access the thumbnail service under the port 9140. See https://github.com/owncloud/ocis-thumbnails/issues/39
