local file cannot sync to Dropbox. Occured Windows event log ID 281

[TurtleDoor]

I'm using Dropbox for Windows 10 Ver 163.4.5456

When my PC runs screen saver, sometimes local file cannot sync to Dropbox.
A Windows event was recorded prior to the loss of sync:
- Log Name: Application
- Source: DbxSvc
- Event ID: 281
- Task Category: (4)
- Level: Error

Is this event the reason to lost syncing?
Is there a way to prevent lost syncing?
