Cyberduck cannot connect to ftp server

MacOS X 10.4.11, Cyberduck 3.2.1.

I have checked common problems and searched the bug report database. I cannot find any mention of this problem.

I can connect to ftp.tex.ac.uk via the Finder.

Attempting to connect to the same server using Cyberduck (anonymous login) results in:

I/O Error: Connection failed.
ftp://ftp.tex.ac.uk
Read timed out.

Before that message appears, I see `Login successful' in the status bar (?) at the bottom of the Cyberduck window, then it announces a retry, then login successful again. Finally, the error message appears.

The transcript that appears is as follows:

230-may be confusing your ftp client.
230-
230-This is the UK node of the Comprehensive TeX Archive Network (CTAN).
230-The other participating hosts in the CTAN and their root CTAN
230-directories are:
230-	dante.ctan.org          tex-archive
230-	tug.ctan.org            tex-archive
230-In order to reduce network load, it is recommended that you use
230-the CTAN host which is located in the closest proximity to your
230-site.  The file CTAN.sites lists known mirrors of CTAN.

230 Guest login ok, access restrictions apply.

I can connect successfully to ftp.tex.ac.uk here. Do you still see the issue? Must be a local network configuration issue.
