Yes, but why?
I mean, I never configured for port 80 before, and certbot always renewed the certs. Am I wrong to suppose that certbot's apache module should auto-configure the virtual host for port 80?
I can manually add port 80 for all virtual hosts (there's more than just the acs example above). However, it strikes me that I never had the need to do so before (and I did not change my apache vhost dir since the last time certbot renewed the certs).
I'll do that and get back to you.
Thanks!
