Hi, I am trying to connect to an SFTP but am getting the following error from Chilkat in the function sftp.Connect(hostname, port)...

I am primarily using the 4 functions to connect to SFTP

sftp.UnlockComponent(ChilkatKey); sftp.Connect(hostname, port); sftp.AuthenticatePw(username, password); sftp.InitializeSftp();

What am I missing ? Thanks for your help.

You are using an old version of Chilkat (As shown by "DllDate: Dec 22 2010" in the LastErrorText). Updating to the latest version of Chilkat should solve this problem.

Hi, Thanks for your response; I used the new version; however, I got "similar" error:
