I am having an issue using dtFTPnetPro connecting to a FTPS site using FTPS Explicit and Passive mode. When I use an external client ( Core Ftp ), it connects and runs just fine, but it takes about 45 seconds to connect. I can't change this since this is a clients FTP server that I have no access on.
I can do the initial connect and handshake just fine, but when I try to open the data connection to do a file list, it times out after 20 or so seconds, regardless of what the Timeout property is set to. Is there something I'm missing, or does the timeout property just not work?
Here is an example log file of what is happening. As you can see, even though timeout is set to 60000, it starts to connect for data transfer at 15:36:04.069, and throws a timeout at 15:36:25.067, which is only 20 or so seconds later, not the 60 specified in timeout.
