Content deployment job 'XXX' failed.The remote upload Web request failed.

During a Sharepoint publishing process I got the following error:

Content deployment job 'XXX' failed.The remote upload Web request failed.

The problem that was occuring was that the account that was being used to authenticate against the central administration of the target server in "Content Deployment Settings" from the source did not have permissions in the destination site collection. I gave that account permissions to the site collection and it worked.
