I have installed the the windows desktop client (2.2.4.2) to sync my NC (11.0.0).  
After entering server, loginname, password, the **initial connection set-up fails** with a webdav error message: “Es gab eine ungültige Reaktion auf eine WebDav-Authentifizierungs-Anfrage” which translates to “ **Bad reply to a webdav authentication request** ”.

- the installation is in [www.mydomain.de/nc](http://www.mydomain.de/nc) and accessed via [nc.mydomain.de/](http://nc.mydomain.de/)
- login/pwd are ok on the web interface
- I tested with a simple password (no special chars), no success.

**What else can I do?**

Did you figure this out? I’m experiencing the same error with my new setup of NextCloud 12. Any ideas?

seems you are not the only guy having this problem.  
I created a new thread here: [Client login fails with 401](https://help.nextcloud.com/t/client-login-fails-with-401/29378/5)  
which was already pirated by another one.

Did anyone of you solve it?
