Unable to connect Discourse and WordPress

When I SSH into the shared server (which is hosted by SiteGround) and manually run a curl command to request my discourse install, I receive the same error message;

“curl: (6)” Could not resolve host: discuss.guidery.com".

I even created a new wordpress site, using a new domain (although on the same Siteground server) without Cloudflare operating DNS and received the same error message.

Any other ideas?
