01
Identify the affected address
Copy the complete URL that fails and note whether the issue affects the main domain, www, or another subdomain. Capture the browser warning and the time it appeared. Avoid changing multiple DNS records while the cause is still being investigated.
02
Confirm domain ownership and renewal
Check that the domain is registered to the intended business owner and that its renewal contact details are current. Share the registrar name and expiry information with the team. Keep ownership approval and payment details under the business owner's control.
03
Review DNS and the certificate together
A domain must resolve to the intended hosting setup, and the certificate must cover the address visitors use. Tell the team about recent hosting, DNS or certificate changes so they can check the relevant configuration.
04
Choose one public website address
Agree whether the public site uses the main domain or www, and ask the team to verify redirects, links and certificate coverage. After changes, check important pages and any sign-in or payment flow through the chosen HTTPS address.
