Error on the daily cron job runs

I’ve been getting an error on the daily cron job runs – “/usr/sbin/csf –u , Oops: Unable to download: write failed: Connection timed out” on a CSF server (CentOS 6). The server did not have any major changes for the past year, so this came as a bit of a surprise to me. So far, I could not find a solution to fix this. Any suggestions?
