this is now in place and the old domains are now using X509 certs of letsencrypt.
Do you know if redmine supports going to HTTPS only (i.e. redir http to https). I changed the "protocol" to HTTPS in the admin panel but that had no effect afaict.
I would prefer to be HTTPS only and also have the session cookie have the "Secure" flag (so they're never sent over plain HTTP)
