Timeout; unable to retrieve directory listing

Using WinSCP version 4.2.8 (and a rather older version) I get Timeout detected, unable to retrieve directory listing.

This is when connected to an office LAN. From home, the same client talks to the same FTP server fine.

With Filezilla, I had the same problem, and solved it by setting Active mode. Filezilla has three options (default, active, passive). In WinSCP, the "passive mode" checkbox is unchecked; changing it makes no difference.

Here is the WinSCP log:

Can you try disabling listing of hidden files?

Thanks for the suggestion, Martin. Is that a WinSCP option? - if so I can't find it.

Please read documentation:
https://winscp.net/eng/docs/ui_login_ftp

Your suggestion solved the problem. Many thanks.

(It took me a while before I could test it because the failure is only occurring when I connect via one particular network).

Disabling "show hidden files" solved the problem THX

Hi,

I'm using WinSCP 4.2.8. I'm trying to connect through FTPES to a IIS Server.
Note that simple FTP is working.
