Directory listing is taking an abnormally long time for me when I connect to our FTP server using Auth TLS or AUTH SSL, but
SFTP works in a matter of seconds. I've tried changing the SSL protocol version (SSLv3 or TLSv1) and neither works. It shows Listing directory, 48 bytes down at the bottom. The connection eventually times out.
In this attempt, i have FTP using Explict SSL (Auth TLS) selected with SSLv3. The server is running GlobalSCAPE Secure FTP 3
