I use a cname to point to the acme\_domain that is used to deploy Pritunl and would like to included that when Lets Encrypt makes the cert request. ---

The Lets Encrypt domain option can include a list of comma separated domain names. ---

Do you have an example? Every time I try that it always concatenates them into a single string and validation fails. Just for reference vpn.stud in this case would be a dynamic url that gets generated and vpn.stage would be the cname. No matter how I enter them in the Domain field they always get joined together. Pretty sure the CLI command does the same thing.

Actually for Pritunl it is only one domain. Pritunl Zero and Pritunl Cloud have support for multiple domains but not the VPN server.
