We have a domain
example.com on AWS Route 53, that is our authoritative DNS. We also use Cloudflare for security, so our domain goes through Cloudflare.
I've found that whenever we create any subdomains, whether it be
app.example.com, these CNAME records must also be added to Cloudflare in order for them to work. Many people have said it's not required, but the page throws a 404 error every time if the subdomains are not added to Cloudflare.
So that was fine at the time, I added them to Cloudflare and everything loaded up. But now I am encountering an issue. For
med.example.com, we are using an LMS system called EthosCE. There are certain features like SCORM and a course overview dashboard that are not loading because of Cloudflare.
Is it possible to remove my subdomain from Cloudflare altogether and still have it load?
I tried using page rules to disable literally everything on the subdomain, but it still gives the 404 error when I try to view the dashboard. (The rest of the site works, it's just certain parts of it that seem to be encountering problems because of Cloudflare.)
