We updated the ChilkatAx version from 9.4 to 9.5 several months ago. We use this mainly for automated SFTP uploads to a remote server.
We've been having some issues lately, so in looking thru the logs I have noticed that although ChilkatAx is running a newer version its still using an older build of PuTTY for SFTP.
Log is here:

Chilkat does not use PuTTY's implementation. Chilkat's implementation is proprietary and not based on open source implementations. What you are seeing is the default value of the ClientIdentifier property, and this is described in the online reference documentation. In addition, 18.104.22.168 is still an older version from Aug 1, 2004.
