Cloud Sync Never Finishes

[photomatix]

I have a sync task set up with google drive but it never seems to finish. It gets to around 99% and gets stuck. I've got about 200gb to sync and let it run for several days. I have a 1gbit connection so it should only take a few hours. I never get any logs because it never finishes, unless I'm looking in the wrong place.

I'm able to create a manual rclone job via the cli and never have any issues with that.

I'm opened for any suggestions.
