Cant connect to SFTP-Server - old winscp version is working!
hello,
strange problem: using winscp v4.1.9 (build416) to connect to NullFTP-Server (v1.0.3.3) is working fine with SFTP (fallback SCP).
with winscp v4.3.5 (build1463) the client connects to the SFTP server and refuses with following log (debug mode 2).
on the server side it looks like this (nothing special):
the connection attempt was done locally on a win 2008R2 server with NullFTP bind to the 10.192.37.225 IP / interface.
can anyone help - i really don't know where to dig up.
thanks in advance, ciaccom
