Log Review Script Assistance

I'm trying figure out what the problem is with this script. I'm able to transfer a file with GUI - and used the "Generate Code" for the session as a basis for the script.
Authentication is working fine but the target file won't download. I'm not sure if there's a particular parameter to add for timeout or something. Any assistance in pointing me to next steps would be greatly appreciated.
Attached file includes script (less the connection string) and excerpt of log file output.
