FTPS from iSeries to a Windows system running GlobalSCAPE EFT v6.0

We are trying to ftp a file from the iSeries to a windows server running
GlobalSCAPE EFT (v6.0). We are using FTP *SSL and we keep getting the
following message "Attempt to open connection failed." We can connect but
when we try to send or receive data we get the message. We have tried
SENDPASV 0, with no success.

We can connect and send using normal FTP (NON-secure).

We can connect and send using FileZilla. see log below (last one).


IBM support suggested it might be a firewall issue but we confirmed that
it is not (as we do utilize other FTPS instances). We have contacted the
FTP server's tech team and at this point they are contacting GlobalSCAPE.
We think it's at their end but just want to be sure there's nothing on our
end that we might be overlooking.

Below are the session details for three different FTP attempts from the
iSeries (V5R4). All three end with " Attempt to open connection failed.",
and you can see the login was successful.
