Datto Drive Error: "Connection closed / Operation canceled"



You receive the error message "Connection closed / Operation canceled" when sending certain files.  


  • Datto Drive


  • Directories or files deleted from the source computer are not updated on the source
  • Datto Drive database file could be corrupt
  • These errors could be caused by issues with particular files or folders (corruption, being constantly in use. etc.) Certain file types, notable PST's Quickbooks, will cause this type of issue. 


1. If directories or files were deleted from the source computer but still show in the subdomain, delete them from the subdomain.

2. Enable desktop logging to help narrow down the issue

3. Verify the files that are failing still exist at the location. If the files still exist in the location, the Datto Drive database is corrupt. Perform the following steps to resolve this issue. 

4. Exit the Datto Drive app completely

5. Find the ._sync_*****.db or .csync files
Right click the sync connection > open folder > view hidden files

6. Delete all of the ._sync_*****.db or .csync files for the share

7. Restart Datto Drive

8. Attempt to send the files again

9. If the send still fails, exclude the files showing as problematic in the desktop log and try sending again.
