Description (last modified by dkocher)

Cyberduck 5.4.4. on OSX 10.11

Whenever I download a folder containing multiple item I get intermittent failures with message :

"Interoperability failure: 502 Command not implemented PASV, ..."

This happens at different time on different files meaning some of the file is downloaded correctly in spite of the message some of the download is instead aborted. Retrying multiple times or using command line FTP mget works fine instead. Never had this problem in past with same FTP site and same data types.

The Log is here below as well as screenshot of the error:

Can you try to set the Connect Mode in the bookmark to Active (PORT) as the server does not seem to support Passive (PASV) FTP connections for data transfers.

comment:4 Changed on Jun 7, 2017 at 2:47:54 PM by dkocher

Also try to limit the number of connections allowed to 1 for file transfer in the bookmark setting Transfer Files: Use single connection.

Strange as the server has not changed and it used to work, however I'm inside corporate network and they might have changed the firewall they use. Anyway:

1) I just tried with PORT ACTIVE and it still randomly drops out. (note that also with PASV and insisting after a while it gets through..) 2) with one connectcion at time it also times out. (see new attachment).

Might be our firewall acting funny, but maybe some robustness in Cyberduck could help (and in the past years there was nevere a problem)
