TLS 1.3 session reuse not working

2021-06-27 03:57

Hi, I'm running an FTP server with vsftpd 3.0.4 and when TLS 1.3 is enabled and TLS session reuse is required for data connections, WinSCP isn't able to establish data connections after the first initial directory listing.

This is with the latest WinSCP 5.19.

Server asks for authentication with a client certificate.
Disconnected from server
Could not retrieve directory listing
SSL connection failed: session reuse required

Please post a complete log file.
Is there anything useful in the server-side log?

I've attached the WinSCP debug log file, along with the debug log from vsftpd.

May I get a test account on your server?
