+# Configuration file for Let's Encrypt ACME Challenge location
+#############################################################################
+#
+# This config enables to access /.well-known/acme-challenge/xxxxxxxxxxx
+# on all a Web site (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!
