Renewing a certificate does not always mean the renewed version is already active on the live site. A renewal check helps confirm what visitors are actually receiving.
Auto-renewal or manual renewal can complete in one place while the live server still serves an older certificate.
Run it after any renewal event, especially if the previous certificate was close to expiry or if browser warnings persist.
Compare the served certificate validity dates with the expected new renewal period to confirm the updated certificate is live.
Common issues include old certificates still being cached by server config, incomplete deployment, failed service reload, and multiple servers not updated consistently.
Once you understand what to look for, run a live check using the tool below.

Check the live certificate details and compare them with the expected new validity dates.
This page explains the purpose of the check, what results mean, and what problems to watch for before you run the live tool.
