Re: right config for letsencrypt

since i do this through haproxy, it will be a little different, but where
ever port 80 is open to you can have a block that does the following
so in the http block of haproxy i send it to a backend when it meets
these requirements.

acl letsencrypt-request path_beg -i /.well-known/acme-challenge/
redirect scheme https code 301 unless letsencrypt-request
use_backend letsencrypt-backend if letsencrypt-request

Which sends the request to a local nginx instance (on the live haproxy
server) that can validate the cert b/c server_name = _; I generate these
regularly, so my setup is a little different, but

server {
listen 8888 proxy_protocol;
server_name _;
charset utf-8;
set_real_ip_from {{ servers.lb.master.ip }};
set_real_ip_from {{ servers.lb.slave.ip }};
real_ip_header proxy_protocol;
root /var/www/html;
location ~ /.well-known {
allow all;
deny all;

in a regular, single server nginx setup, i use the following block:

server {
listen 80 default_server;
listen [::]:80 default_server;
server_name example.com www.example.com;
location ~ /.well-known {
allow all;
return 301 https://www.example.com$request_uri;

So it will only redirect if its not a lets encrypt request. HAProxy may
mean nothing to you, but it shows an alternate configuration. And of
course Francis is correct, you need 80 open.
