I'm running into the following error and looking for more information as far as what's going wrong? I have no problem to connect with a sftp client, but with biztalk it doesn't work att all.

Thank you for contacting us.

The error says that the server has identified itself in a wrong way. Are you sure that there is an SFTP (not FTPS) server running on the remote side?

It's an SFTP server on the remote site. When a use a client (Altap Salamander), I get following driver information:

Code
Session protocol = SSH-2
SSH implementation = SFTP
Encryption algorithm = blowfish
Compression = No
File transfer protocol = SFTP-3
------------------------------------------------------------
Server host key fingerprint
ssh-rsa 1024 54:00:1e:aa:15:81:72:e1:bc:1a:c9:8a:8b:3b:dd:6b
------------------------------------------------------------
Can change permissions = Yes
Can change owner/group = No
Can execute arbitrary command = No
Can create symlink/hardlink = Yes/No
Can lookup user groups = No
Can duplicate remote files = No
Can check available space = No
Can calculate file checksum = No
Native text (ASCII) mode transfers = No
------------------------------------------------------------
Additional information
The server does not support any SFTP extension.


Doesn't my version (SecureBlackBox for Biztalk - v 6.0.144) support the combination of protocolls and encryption?
