Here’s how you can add a CNAME in cPanel:

  1. Sign in to your hosting account’s control panel

  2. Make sure the subdomain does not exist yet, otherwise delete it or choose a different subdomain

  3. Open the DNS zone editor

  4. Add a new CNAME record with these settings: 

    • Host: clients

  5. Save your changes

You can find detailed instructions with screenshots on the cPanel website.
