Use your registrar's web interface to copy the DNS target values from the access details you received, then check HTTPS, the public site, and email before you publish the address.
Collect the details first
Make sure you can sign in to the domain registrar. Write down the current DNS records before you edit them. Note which service handles email. Keep the domain name, app name, and DNS target values from the access details together. Do not guess an address or copy a value from an unrelated site.
Point the domain carefully
In the registrar's web interface, update the records needed for the root domain and any www address you plan to use. Make only the changes required for the app. DNS changes can appear at different times in different places. Wait for the DNS change to appear before judging the final result, and check it from more than one connection instead of assuming that one browser view is complete.
Check HTTPS
The WordPress setup guide places DNS, a certificate, and forced HTTPS in the same setup chain. When the domain points correctly, open the site with HTTPS and test each hostname you plan to publish. Check that the browser shows no certificate warning and that the site does not fall back to an insecure address. Report any certificate warning.
Test the important paths
- Open the root domain and the www version if you use both.
- Open the public home page and the admin sign-in address.
- Check images, links, forms, and any shop or course action.
- Send a safe test message if the app sends email.
- Check that the final page address is the one you want to share.
Protect mail records
Do not remove mail records just to make the website work. MX records direct mail. SPF, DKIM, and DMARC help receiving systems check outgoing mail. If another service handles mail, keep its records while you connect the website. A domain change can break password resets or contact forms when mail records are lost.
Use a guide and ask for help
The WordPress setup guide gives the plain-language context for DNS and HTTPS. If the target, certificate, or records are unclear, send the domain and the exact warning through the support form. Never include a password or private key.
