![]() At this point fz server closed the connection with "425 TLS session of data connection not resumed." -ve response. The first cc handshake worked as expected but dc handshake for the subsequent list operation reported that (SSL_session_reused->false) it was actually a new TLS connection. It all worked fine till I tried the code again after 2 years (yesterday) on the latest gnutls based FZ and got this issue. I had a stable working openssl based FTPS code which I had tested for session resumption against the older filezilla servers (presumably openssl based as well). In my case it failed under slightly different circumstances which I believe is worth highlighting. The exception message could be translated as "Unhandled Exception: 32Exception: The client and server cannot communicate, because they do not possess a common algorithm"".
