SFTP Error 10058 Connection lost

I am trying to connect to an internal SFTP server using the SecureBlackBox TElSimpleSFTPClient.Open method but keep getting the error Connection Lost (error 10058).

In discussions with our interal support group I was told that we need to use the "SSH_EXEC" method to connect. I assumed this was a property setting but I was unable to find it. I was unable to get a clear answer from our support group as they are unfamiliar with SecureBlackbox.

Do you know what they are referring to when they mention "SSH_EXEC" and how does it apply to SFTP.

Unfortunately your description of the problem is at least confusing. I would suggest going a different route. "Connection lost" error happens when the server gets confused by the request and doesn't properly handle this situation (most servers are buggy and don't respond with error code, as the standard requires - they attempt to run and hide by forceful closing of connection).

So before we continue,

1) try checking the server log after you attempt to connect. It might have explanation of what happens.
2) run the sample application (SimpleSFTPClient demo) and capture it's log. We need to know, on what exactly stage connection is closed.
3) I suggest to check with your advisors, what they meant by SSH_EXEC

Sincerely yours
