In FlashFXP 3.6.0.1240, when using a Socks 4 Proxy to connect to an SSL enabled Server, Secure Directory Listing works fine:
Code:
[R] PWD
[R] 257 "/" is current directory.
[R] TYPE A
[R] 200 Type set to A.
[R] PROT P
[R] 200 Protection set to Private
[R] PASV
[R] 227 Entering Passive Mode (*,*,*,*,16,1)
[R] Opening data connection via Proxy
[R] LIST -al
[R] Connected. Negotiating TLSv1 session..
[R] 150 Opening ASCII mode data connection for directory listing using SSL/TLS.
[R] TLSv1 negotiation successful...
[R] TLSv1 encrypted session using cipher DHE-DSS-AES256-SHA (256 bits)
[R] List Complete: 548 bytes in 0.67 seconds (0.8 KB/s)
Trying the very same server, with exactly same options (imported from FlashFXP 3.6.0.1240 through tools->backup) I get an SSL Error:
Code:
[R] PWD
[R] 257 "/" is current directory.
[R] TYPE A
[R] 200 Type set to A.
[R] PROT P

Connecting without Proxy to verify the Issue appears to be within the Proxy Implementation:

The proxy server used for those tests is danted:
