We typically don't put opening braces on a new line in nginx configurations,
likewise below.

+    auth_basic "Stats Restricted Access";
+    auth_basic_user_file /var/www/htpasswd;
+  }
+
+  location /update
+  {
+    auth_basic "Stats Restricted Access";
+    auth_basic_user_file /var/www/htpasswd;
+  }
+
+  location /notification
+  {
+    auth_basic "Stats Restricted Access";
+    auth_basic_user_file /var/www/htpasswd;
+  }
+}
