[quote="mhermann"]Hello

I'm unable to use "TLS explicit encryption" by connection to an FTP server. WinSCP connects to the server, but then it's obviously unable to get the directory: "Could not retrieve directory listing". I get the same message for "SSL explicit encryption".

I've already tried passive resp. active mode and "Force IP address with passive mode connections". Then I've tried it with WinSCP version 4.3.5 and 5.0.2beta on two different PC's. And I've read https://winscp.net/eng/docs/message_error_listing_directory

Nothing helps :cry:

Only Cyberduck (https://cyberduck.io/) seems to works!

Here's the WinSCP log:

Additionally, here's the log while connecting to the same server with CyberDuck. It's not so informative as the one generated by WinSCP but maybe it helps you anyway...

Hello Martin. I've just sent you an email. Thank you for sending me a debug version of WinSCP.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.
