Uploading files on SFTP

I was working with a TextDrive server, and every time I've tried to upload a folder drag'n'drop through SFTP, it disconnects. Then, I resume, it goes until the next subfolder is uploaded, then disconnects. Rinse and repeat.

Duplicatable. Every folder causes a disconnect. Hitting resume causes it to start again, until the next folder causes a disconnect.
