I am accessing an FTP server I have no configuration access to. Initially the connection is fine, and then the server appears to start refusing to grant me directory listings. Excerpts from the log below.
This link describes the same behavior and the "session reuse" description fits the symptoms I am seeing:

Is there an option in FZ client to reuse SSL sessions?
