Your server is returning a 400 for a PUT. That's all we can tell you. You'd have to check the server logs to see why.

I don't think I can check the server logs, as the cloud provider GMX does not grant me access to them.
I tried uploading a file using curl.exe, and that worked: I found the file online in the cloud storage. So, I am wondering what is causing the problem.

curl.exe -u "USERNAME" -X PUT -H "Content-Type: application/x-www-form-urlencoded" --data " " https://webdav.mc.gmx.net/zotero/zotero-test-file.prop
