From your packet trace it looks like that FTP server is firewalled with
a firewall that rejects passive FTP connections. Not a nice thing to do
if the FTP server is configured to accept the PASV command (used to
initiate a passive connection).

Squid can gracefully handle that the PASV command is not supported or
not permitted, but it PASV is accepted by the FTP server then it is
assumed that a passive connection may be opened. It does not currently
retry the data channel using PORT is the passive connection fails after
PASV has been accepted.
