SSL Certificate Health Checker
Look up the unexpired SSL certificates issued for your domain in Certificate Transparency logs: issuer, validity dates and days to expiry.
Lists unexpired certificates for this hostname from public Certificate Transparency logs (via the Cert Spotter API). It can't see which certificate your server actually serves or how TLS is configured; for that, click the padlock in your browser or run openssl s_client -connect host:443.
