Fwupd-refresh.service failed and nginx unkown directory

I have the following error on nginx after the command "nginx -T":

nginx: [emerg] unknown directive "n /etc/nginx/sites-enabled/h.servicesystemctl cat fwupd-refresh.service:1

nginx: configuration file /etc/nginx/nginx.conf test failed

Is it a bug, or ?
