Transferring many files via TLS/SSL fails

Hi,
when transferring a folder with many files and a bunch of subdirs via SSL or TLS to my server, I get the following error message after a while:
Error transferring file...
The server cannot open connection in active mode. If the problem persists, consider switching to passive mode.
Copying files to remote side failed.
Unable to build data connection: Operation not permitted
The connection is set to passive mode, so I think there must be a problem, that WinSCP causes to "forget" this...
When I transfer the same directory in FTP mode (without encryption) it works fine.

Any solution for this?

Re: Transferring many files via TLS/SSL fails

Please post a full log file showing the problem.

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. For posting extensive logs you may use pastebin or similar application. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

Think I've got a little closer to the problem:

After having a closer look to the point where WinSCP throws the error, I figured out that it was when trying to upload a folder conataining two empty (0 KB) files.

However, this only comes up when using SSL/TLS.
With unencrypted FTP it works fine.

Any thoughts?
