Private key works in GUI but not console

I am trying to script a transfer using a private key. Everything works fine when using the GUI but the key does not authenticate when scripting the connection.
The private key is configured both in WinSCP and Pageant.

Here is my command line:
"c:\Program Files (x86)\WinSCP\WinSCP.exe"  "/console" "open USER@HOST.com" "-privatekey=G:\Documents\Key2.ppk"    

And the resulting log file:

Please attach a complete log file both from GUI and script.
