From what I can read from these console errors it seems that the plugin fails to contact Dropbox due to network connectivity issues. Have you experienced problems with any other plugin due to this?
Only from DriveBackupV2, and also it sometimes happen durning some player are playing. So the server must be connected to the internet.
