# Include location directive for Let's Encrypt ACME Challenge
include /etc/nginx/snippets/letsencrypt-acme-challenge.conf;

#############################################################################

# Configuration file for Let's Encrypt ACME Challenge location

# This file is already included in listen_xxx.conf files.

# Do NOT include it separately!

#############################################################################

#

# This config enables to access /.well-known/acme-challenge/xxxxxxxxxxx

# on all our sites (HTTP), including all subdomains.

# This is required by ACME Challenge (webroot authentication).

# You can check that this location is working by placing ping.txt here:

# /var/www/letsencrypt/.well-known/acme-challenge/ping.txt

# And pointing your browser to:

# http://xxx.domain.tld/.well-known/acme-challenge/ping.txt

# Rule for legitimate ACME Challenge requests (like /.well-known/acme-challenge/xxxxxxxxx)

# We use ^~ here, so that we don't check other regexes (for speed-up). We actually MUST cancel

# other regex checks, because in our other config files have regex rule that denies access to files with dotted names.

location ^~ /.well-known/acme-challenge/ {

    # Set correct content type. According to this:

    # https://community.letsencrypt.org/t/using-the-webroot-domain-verification-method/1445/29

    # Current specification requires "text/plain" or no content header at all.

    # It seems that "text/plain" is a safe option.

    default_type "text/plain";

    # This directory must be the same as in /etc/letsencrypt/cli.ini

    # as "webroot-path" parameter. Also don't forget to set "authenticator" parameter

    # there to "webroot".

    # Do NOT use alias, use root! Target directory is located here:

    # /var/www/common/letsencrypt/.well-known/acme-challenge/

    root         /var/www/letsencrypt;

}

# Hide /acme-challenge subdirectory and return 404 on all requests.

# It is somewhat more secure than letting Nginx return 403.

# Ending slash is important!

location = /.well-known/acme-challenge/ {

    return 404;
