I have one master LE certificate and within the certificate I have several subdomains with certificates. Its not a SAN like certificate – I’ve individually included all the subdomains I’ve needed.
I believe I’ve recently upgraded all the certificates for the next 90 days, however I keep getting notifications that a certificate is due for renewal. I imagine I’ve missed one of the subdomains if anything.
How do I check what actual certificate needs renewal? My master domain is gohilton.com.
Connect to the site using the cert mentioned and compare the cert expiration date.
If you can, I would also list all the certs in use and review their "coverage".
Check for overlapping names and delete any unused/unnecessary/expired certs.
