This environment cannot connect global ipv6 sites.
WinSCP version 4.3.2 doesnt fallback to ipv4.
I have sent you an email.I have a similar problem. The host I want to connect to has IPv4 and IPv6 but when its sshd only listen to IPv4 I get "connection refused" error if I use "auto" internet protocol version. Putty 0.60 has no problems to connect.
