Snapshot doesn't upload to Google Drive

Hey there,

I've created a Snapshot that should send all snapshots made to my Google Drive, however after i let it run it gets stuck on the uploading. Here is a link so you can see the status the Snapshot gets stuck on. https://snag.gy/raNTwS.jpg

Do you have any idea why this is happening? I've unlocked support access for http://www.patservice.eu/beheer so you can get in and see for yourself.

Thanks in advance,
