Cannot upload file in BOX

Hi Sarah, 

Welcome to the Box Community, I'm happy to help!

Have you tried to connect to Box using other network to see if this makes any difference?

I would also recommend checking out this article for more troubleshooting tips on issues with upload: Troubleshooting Uploads to Box 

Hope it helps! 

Regards, 

We have the same issue - Box Drive in China shows pending uploads for the app.
Web uploads work, but sync from Box Drive errors and does not upload - any ideas?
