It appears your DNS configuration for getdohq.com confused Cloudflare a bit.
Your CNAME generally points to a host which is not on Cloudflare and which resolves. That host’s domain is not on Cloudflare either, however it seems you added that domain at one point to Cloudflare and still have it active there, even though the domain itself does not point to Cloudflare any more.
In order to get this working you’d either need to remove the getdohq.com from your Cloudflare account or move the domain properly to Cloudflare.
