Hello mragusa,

thanks for your answer. I’m not sure to understand your answer. If I understand, I can generate with Let’s Encrypt a certificat for both hostnames?



In order to use SSL for both hostnames, you will need to generate one certificate per hostname but you can use the SAN field in the SSL certificates to define the www alias.

Please let us know if there is anything else we can help you with.
