Staging Copy Not Working

My host (Siteground) says the staging site I created is not working because my DNS is not pointed correctly.

I entered their A record IP address and CNAME www for my web address in the Cloudflare DNS set up.

When I check the DNS, there is a check on everything except for Seol Korea.

I made this DNS change yesterday (Sunday evening).

Is what they are saying accurate? I do intend to wait another 24 hours, but I want to prepare if an issue were to persist.

Toggle the DNS entries to :grey: DNS Only, then wait five minutes to take effect. Then your DNS will point directly at Siteground.

Thanks for your reply. I toggeled the A record and CNAME (www) to DNS only and left for a while and the staging copy still has a DNS error.

Any ideas?
