Certificate expiration for wildcard domains


I've got a couple of expiry bot emails stating the certificate on my domain will expire soon. I don't use the domain (let's say mydomain.com) itself with a website, however I have a number of subdomain websites (abc.mydomain.com, xyz.mydomain.com, etc).

The wildcard certificate is fine and not about to expire and all those websites show no problems with the wildcard certificate.

I thought that wildcard certificates include the domain itself, is that not the case?

Do I need to worry about the certificate for *.mydomain.com when I'm getting expiry notices for mydomain.com?

Thank you!

They might refer to different certificates. If you tell us the domain name we can actually check what's expiring and what's not.


"*.example.com" does not cover "example.com".

You would need to include it in the cert [if needed].
