What you will need:
Important: Please follow the first step of this article before following the instructions on this page.
After adding the subdomain in systeme.io, you need to see the DNS settings in your Cloudflare account
Note: Each subdomain added to systeme.io has its own CNAME records to integrate into the hosting site.
Example:
In this example, we will connect the subdomain example.test-sio.org to systeme.io
You will then need to log in to your systeme.io account and click on your profile picture, then go to Custom Domains and add your subdomain.

First CNAME:

Note: If a CNAME record with the name example already exists, edit its value to dv5xmtsih8vdv.cloudfront.net.
Second CNAME:

Note: To check your records, you must enter the full CNAME name (including your domain name) into the search bar.
CNAME 1 verification:

CNAME 2 verification:

Notes:
- It can take up to 24–48 hours for DNS records to propagate completely.
- Sometimes, your host may not be able to register a CNAME record due to a conflict with other existing DNS records. This usually happens when adding the first CNAME. If you encounter a conflict, contact Cloudflare support to determine if those existing records are required or if they can be safely deleted to allow your subdomain to connect.
