Hello, I am using Ubuntu 14.04 LTS with Apache as per the "perfect server" setup instructions + Letsencrypt SSL. Since years I set "Auto-subdomain" to "www" and it always worked. I have noticed, if: I enable Letsencrypt SSL Under Redirect I enable: Rewrite HTTP to HTTPS then websites get a proper redirect from http to https, however they lose the www auto-subdomain functionality. Example: If I enter: http://www.rsppfacile.it the browser goes to https://www.rsppfacile.it But if I enter: http://rsppfacile.it or https://rsppfacile.it It won't redirect to https://www.rsppfacile.it but to https://rsppfacile.it Therefore, auto-subdomain "www" is not being applied. Any ideas about what could go wrong?
