Launching today, STORM now supports multiple domains with Let’s Encrypt. These additional domains are also known as Subject Access Names or SANs. This means that we can encrypt and secure multiple domains pointing to the same web site using a free Let’s Encrypt Certificate.
We’ve made it really easy to secure additional domains. All you need to do is add an additional domain under the Domains tab on the Web Site configuration. Then under the Let’s Encrypt toggle on the SSL Configuration page you’ll see a smaller toggle for each domain. Just toggle the domains you would like added to the SSL and within a few seconds they’ll be added to the SSL Certificate. Should the process fail STORM will give you a reason why it has failed.
You’ll need to make sure the DNS for the domain is pointing to the STORM server, password protection has been disabled and there isn’t a redirect for this site.
