Error with active transfer (PORT) on TSL enabled FTP

398449a created the issue

I was trying to connect to a TLS enabled FTP site using active transfers, login works, but when I try to download a file, which is where the PORT ... command is issued, I receive this error:

"No available certificate or key corresponds to the ssl cipher suites which are enabled"

I tried with different FTPS, same error, it seems Cyberduck has some problem in creating an SSLServerSocket in order to receive connections back from the FTP.

I can provide a TLS enabled FTP to test the issue.

Thanks for the credentials. I cannot reproduce it here, however. Is there a proxy or firewall in between that may be the culprit?

A second report in #3113.
