Important: Please complete the first step of this article before proceeding with this guide.
After adding the subdomain in systeme.io, you must access the DNS settings in your LWS account.

Example:
In this example, we will connect the subdomain example.team-sio.fr to systeme.io
First, hover over your profile picture, click Settings, then go to Custom Domains and add your subdomain.

Click Manage next to your domain to open its settings.

Scroll down to the Domain management section, then click DNS zone for your domain name.

First CNAME:

Note: if a CNAME record with the name example already exists, edit its value to dgjbhasvg9opx.cloudfront.net.
Second CNAME:

Once the two CNAME records have been successfully added to your host, you can check their status using the following tool: https://dnschecker.org
Note: To check your records, you must enter the full CNAME name (including your domain name) into the search bar.
You should see the same value you added next to a green checkmark, as displayed in the example below. If not, the records may be incorrect. Please review your DNS zone settings.

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 this occurs, contact your host support to determine if those existing records are necessary or if they can be safely deleted.
