"Copying files to remote side failed." Error

After having my computer wrecked by a Windows X update, I am reconstructing my jobs. When I try to synchronize the remote folder, I receive the error "Copying files to remote side failed." What could cause this error?

The error has some more details for sure! Show us a complete error message. Or even better, attach a complete session log file.

I was able to resolve the issue. Thank you for your help.
