Excuse me for putting the same post twice in a row, I was wrong in the topic of my previous post.

Please help me with this query:

I am trying to create an SSL certificate, but it doesn't allow me to create it for my domain with and without www. at the same time.

For example, if I put in HOSTNAME: * .mydomain.com, then a certificate is created for almost all subdomains including www.mydomain.com but not for mydomain.com without the www.

On the other hand, if I put in HOSTNAME: mydomain.com, without the www, just create the certificate for mydomain.com but not for www.mydomain.com

How can I create a certificate that is valid for both the domain name with www. and without www.?
