TLS 1.3 support

#1 Post by xeon » 2018-12-11 20:33

Hello,

When using FileZilla Client on Linux with a version of GnuTLS that supports TLS 1.3, it will fail to establish data connections to servers that also support TLS 1.3. This appears to be caused by FileZilla Client not supporting the new method of session resumption in TLS 1.3.

Cannot reproduce, working fine here including session resumption.

Please post a log with debug level set to 4 of a listing attempt.

Before I buy the Pro version, I'd like to see if FileZilla supports WebDAV/S over TLS 1.3 on an Apache 2.4.37 & OpenSSL 1.1.1a setup. Just recently upgraded my setup.
Testing site is

Please advise, thank you.

No TLS 1.3 in FileZilla Pro yet. WebDAV is working though.
