Issue Use Let's Encrypt on a domain alias

Andrew_Newth

Basic Pleskian
I have a DNN (DotNetNuke) site set up with a few portals running via domain alias. I see under Websites and Domains where it lists the main domain, under that are all the domain aliases set up for the various portals and they all have a Let's Encrypt button. However when I click on this it just has the main domain as the domain to encrypt and no option to use the domain alias instead.

Is what i am trying to do possible with the new Let's Encrypt feature?

thanks!
 
Hi Andrew_Newth,

Is what i am trying to do possible with the new Let's Encrypt feature?
Yes, but not with the Plesk extension.

Pls. read the official Let's encrypt FAQs and documentation(s):

https://community.letsencrypt.org/t/frequently-asked-questions-faq/26 :
Can I get a certificate for multiple domain names (SAN certificates)?
Yes, the same certificate can apply to several different names using the Subject Alternative Name (SAN) mechanism. The resulting certificates will be accepted by browsers for any of the domain names listed in them.

https://certbot.eff.org/docs/using.html#command-line-options
Example usage:

certbot certonly -n -d exampleA.com -d www.exampleA.com -d exampleB.com -d www.exampleB.com


The current maximum for Let's encrypt SAN - certificate - names are:
Code:
maximum is 100
 
I also need this feature to secure CDN sub-domains, maybe on let's encrypt activation page that asks to include "www" plesk can also ask for a list of sub-domains.

Code:
cdn1.mysite.com
cdn2.mysite.com
