Can't backup site with Snapshot Pro plugin

Hi there,
I have tried to backup my site several times but it didn't work. Note: I'm with SiteGround, I'm using CloudFlare with them and also have linked CloudFlare with your Hummingbird plugin. I have activated the Railgun feature within the CloudFlare application in SiteGround. I just noticed that none of my sites are backing up either.

Here is the error message:
==============================
Error 523

Check your DNS Settings. A 523 error means that Cloudflare could not reach your host web server. The most common cause is that your DNS settings are incorrect. Please contact your hosting provider to confirm your origin IP and then make sure the correct IP is listed for your A record in your Cloudflare DNS Settings page.
