Trouble with Multi-Level Subdomain DNS

Hi, I run a website with an example.com.au structure and just set up a subdomain:
green.example.com.au and am getting a “This site can’t be reached” error.

I added the correct IPV4 and IPV6 A and AAAA records but this hasn’t fixed the problem.

I’m aware that multi-level subdomains do not work on Cloudflare - would this url be considered a multi-level subdomain that wouldn’t work on CF?

Hm, do you mean like:

Could be some limitations due to an SSL as written here:

Moreover, are you using Flexible or do you already have SSL certificate at your origin for the desired sub-domains, meaning that you use Full SSL at Cloudflare?

If not, I beleive you would need to pay $10 for a dedicated SSL certificate at Cloudflare or to be on the Business Plan so you could import your SSL certificate that covers all of them and have it resolved successfully.

No, that shouldn’t be. You can tell if it fails that test if you see two subdomain levels in that DNS record:
