Desktop and Mobile clients
The Nextcloud desktop and mobile clients can be downloaded from https://datashare.mpcdf.mpg.de/settings/user/sync-clients.
During the initial setup, just enter datashare.mpcdf.mpg.de as the server address.
More information can be found in the Nextcloud documentation.
Third-party WebDAV clients
Various third-party WebDAV clients are available and are often natively integrated into the operating system.
Some work better than others, especially the integrated Windows WebDAV client has some known problems.
For more information, refer to: https://docs.nextcloud.com/server/latest/user_manual/en/files/access_webdav.html
Third party client will generally not support the now mandatory two-factor authentication.
To work around this, you may create a Device Password (formerly known as “App Token”) in the web UI.
