I am in the process of trying to get a subdomain on our site to point to a site hosted by Cloudflare, however it is getting blocked. The subdomain that I am trying to create a (DNS-only) for with Network Solutions is podium.organ.org but when you access the site it gives a DNS error from Cloudflare. The error is a 1001.
There is a slightly funny setup here, with one domain being a CNAME of a domain that is itself on a Cloudflare CNAME Setup.
% dig podium.organ.org
podium.organ.org. 7200 IN CNAME auth.podium.com.
auth.podium.com. 300 IN CNAME auth.podium.com.cdn.cloudflare.net.
auth.podium.com.cdn.cloudflare.net. 300 IN A 126.96.36.199
auth.podium.com.cdn.cloudflare.net. 300 IN A 188.8.131.52
You have a few options here. You can add organ.org to Cloudflare using a partial/CNAME setup as you have done for podium.com. Alternatively, you could add podium.organ.org as an SSL for SAAS hostname.
