When I try to connect to a server with FTPS support, passive mode makes transfers hang. Hang happens both over IPv4 and IPv6. The connection status shows as "ESTABLISHED" in netstat on both sides. The problem doesn't occur without AUTH TLS, works over both IPv4 and IPv6. The problem doesn't occur with active mode neither, works over both IPv4 and IPv6. Server: ProFTPD 1.3.5, configured for FTPS The client is on the same network with the server, no firewall between them. FileZilla can transfer encrypted data in passive mode without problems. Reproducible: Always Steps to Reproduce: 1. Server with FTPS. 2. ftp -p 3. ls Actual Results: Connected to [...]. 220 ProFTPD 1.3.5 Server [...] Name [...]: **** 234 AUTH SSL successful [SSL Cipher ECDHE-RSA-AES256-GCM-SHA384] 331 Password required for **** Password: 230 User **** logged in Remote system type is UNIX.

FileZilla can connect without problems.
