CyberDuck WebDAV hides files with [tags]

[sorenr]

I have a directory with two files: visible{t}.pdf and invisible[t].pdf

When I connect via WebDAV and browse the directory I get warnings, and invisible[t].pdf doesn't display:

2025-10-02 18:30:58,477 [Thread-56] WARN ch.cyberduck.core.dav.DAVClient - Ignore resource with invalid URI /webdav/downloads/test/invisible[t].pdf

The problem is that [ and ] are reserved characters used for IPv6 addresses cannot appear unencoded in the path component of a URL. My host is using the nginx WebDAV module (ngx_http_dav_module), which doesn't automatically encode URIs.

Would it be possible for CyberDuck to detect this type of invalid URL and fail more gracefully?

This is a bug in the WebDAV server implementation to be fixed. Duplicate for #13864.
