Connecting your own domain means adding one record where you bought it (your registrar). The record is always the same; only the buttons change. This page shows where they live at the ten most common registrars. For the full flow, start with Connect your domain.
Elentir’s Add domain panel shows the exact values on two tabs, CNAME and A:
You want to use
Add this
Name
Value
A subdomain, like www.yoursite.com
a CNAME record
www
cname.elentir.app
The root, like yoursite.com
a CNAME (if allowed) or an A record
@
cname.elentir.app or 51.81.153.211
Some DNS providers allow a CNAME at the root (Cloudflare does, and providers with ALIAS records like Namecheap and Porkbun); many refuse it. If yours refuses, use the A record, it works everywhere. When you enter a subdomain in the host/name field, type only the label (www or app); nearly every registrar adds your domain for you.
Verify keeps failing (status stays Pending or shows Failed). Did you click Verify in the Add domain panel after adding the record? If yes: DNS has not spread yet, or the values do not match exactly. Check them against the panel, test at dnschecker.org, then try again later.
Cloudflare: no verification, no padlock. The record is likely Proxied. Switch it to DNS only (grey cloud).
You created www.yoursite.com.yoursite.com. You typed the full name in the host field. Enter only the label.
Your registrar refuses a CNAME on the root. That’s normal, many do. Use the A record from the panel’s A tab instead.
The old parking page still shows. A leftover A or CNAME record is fighting yours. Remove the registrar’s default records on the same host.
