Snapshot Pro > Managed Backups is not working.

Snapshot pro is not working. When going to managed backups and then clicking on 'backup now', it starts showing the steps incrementing, but then in a short period of time it gives the error saying something under the lines of "Aw shucks, something went wrong :slight_frown: Instead of the beautiful response we expected, we got this: "<empty response> I have played with the config.php file adding "
define('ALTERNATE_WP_CRON', true); " but that has not helped. We do not want you to change ANYTHING. but would like for you to give us suggestions of step by step of what could be going wrong and any solution for it. Thank you!
