[BUG] WebDav Connection to local webdav server fails since last Duplicati container update

[pin00b]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When testing a connection to another container which is supplying a local webdav server (internxt/cli), the connection fails. The last container version worked without any flaws. When I connect to the exact same webdav server via cadaver from another computer, the webdav connection still works, so obviously no problem with the internxt/cli container

Expected Behavior

Working connection to the internxt/cli container supplied webdav server as a backup destination

Steps To Reproduce

Unraid 7.1.1
Duplicati latest linuxserver.io container
internxt/cli 1.5.3 local webdav server
trying to connect to the webdav server container with Duplicati fails since latest Duplicati container update

Environment

- OS:Unraid 7.1.1
- How docker service was installed: via CA/Apps

CPU architecture

x86-64
