That usually pops up when CP tries to send a nzb-file which is not available, i.e.: The nzb provider might be down or the file not available. This could also be happening if you reached your NZB-Downloadlimit on that provider - so CP would actually be able to search for something, recognise it and pass it to sabnzbd (mind: at this point, no nzb file has actually been downloaded), sabnzbd then goes on and tries to fetch the nzb but is unable to due to the reached limit.
Edit:
Oh, and don't forget to triple check sabnzbd's hostname/port, credentials, etc.
