# Communication Error

 * Currently, the site has a daily backup, with the PRO version.
 * For the past 5 days a backup could not happen, this error happens in the settings“
   Backup stopped due to server communication error” with a link “Resume Backup”
   next to the link.
 * When clicked the message goes away and says “Success” with a link “Test Again”.
 * On the “Backups” page at the top, the loading bar says “Processing Files”, but
   sits there, a couple hours later the error comes back up.
 * Any ideas?

 * Hey [@actualtiff](https://wordpress.org/support/users/actualtiff/),
 * I’ve emailed you about this issue, please check it out and let me know. Based
   on that we’ll be able to help you further. Just one thing that I forgot to mention
   earlier, please check if you have whitelisted this IP : 52.33.122.174 on your
   server.
    If you are running WordFence or iThemes on your WordPress site, make
   sure you whitelist the IP there too!
 * Let’s continue our conversation via email so as to avoid redundant replies on
   two channels, thanks for understanding!
 * Cheers,
    Tauseef

 * Why do we need to whitelist 52.33.122.174? TQ

 * Hi,
 * The backups are triggered from our server which has the IP 52.33.122.174. We 
   need to communicate to your WP site for us to run the backup seamlessly and reliably.
 * Thanks
    David.
