Topic "Unable to connect to SFTP site"

Hi,

I'm struggling to create a connection to an SFTP server.
I've got it working on my local computer (which is directly connected to the internet) but can't get it to connect on our servers.
Firewall on the server is fully off, ping returns external ip of SFTP server and I can open a telnet session on it.
But somewhere just before choosing a key exhange algoritm, it goes south.
I'm not sure what to ask our netwerk guy because he will say that port 21 is open.

WinSCP Version 5.1.4 (Build 3020) (OS 6.1.7601 Service Pack 1) - windows Server 2008 R2 standard SP1

The top log is from the server, the bottom one from my local machine.
All events preceding this are identical (except socket number).
Full logs are included as attachement.

Any idea's?

Regards,
Sven Peeters

Are you able to connect using any other SSH client?

Also note that SSH server should be running on port 22. Port 21 is for FTP. Though that could be an issue only in case there's some proxy/firewall/anything on the way, trying to interpret the connection as FTP.
