I’m trying to configure a Duplicati backup to Hetzner’s storage box via WebDAV and keep getting the following error: “Error listing content: Response status code does not indicate success: 401 (Unauthorized).”
A WebDAV connection can successfully be established from a Macbook and/or Linux system if the prefix for the server address/URL “https://” (like https://xxxxxx.your-storebox.de) is used, which is impossible from my Duplicati server, as it enforces the use of “webdav://xxxxx”
The webdav:// prefix is just a way to choose where to connect in Duplicati, internally it will use http:// or https://.
In the WebDAV options, make sure you toggle “Use SSL” as that will result in an https:// connection. Use the xxxxxx.your-storebox.de as the hostname.
The 401 error indicates that the username or password is incorrect. Alternatively, that the method for authentication Duplicati uses is not compatible with the destination.
Hetzner‘s technical support has confirmed, there is eventually an issue with passwords containing some (German?) special characters (I. e. Äöü …) which was the case indeed.
Funny, you can create an access password within Hetzners administrative web console, which eventually will also contain one of these characters and it seems to me there are some more special signs which might cause authentication errors, and too long passwords as well. Up to now there’s no documentation about it, so one has to find out by try and error.
