I get an error, if I try to connect with FTP SSL in passive mode with WinSCP. There are no problems with FileZilla. There is a difference between both logs.
PWD 257 "/" is the current directory Retrieving directory listing... TYPE A 200 Type set to A PASV 227 Entering Passive Mode (85,158,176,225,132,209). LIST -a 150 Opening ASCII mode data connection for file list SSL connection established 425 Unable to build data connection: Operation not permitted Could not retrieve directory listing Retrieving directory listing...
answer: 257 "/" is the current directory command: TYPE I answer: 200 Type set to I command: PASV answer: 227 Entering Passive Mode (85,158,176,225,163,118). command: MLSD command: 150 Opening ASCII mode data connection for MLSD answer: 226 Transfer complete
Can you get the clue?
By the way: your WimSCP is a great piece of software.
