bestsync.us

I have several items set up to sync (3 uploading to SFTP and 1 downloading
from SFTP) and the download item never copies anything down to the local
drive.
We are using V12.0.0.9 on Win 7.
It always seems to show as Success 0 and Failed 0, yet when it syncs it
seems to identify all 247 files that should sync.
It seems to sit at the "Synchronizing..." message for a while and then
quits with the 0 success and 0 failed message.
If I look a the log on the task itself it has a message:
SFTP Error:BestSyncLog: Connect: DllDate: Aug 3 2011 ...

From the service.log file:
SVC:2017/04/25-09:24:01,Start task. C:\shared$\log <== SFTP:/download/log
