Renewal of letsencrypt does not restart/reload nginx
When renew letsencrypt certificates from domains in nginx service the nginx service will not restart in debian9. So it may happen, that a non valid certificate is send by nginx to clients instead of the newly generated one.
After renew of letsencrypt nginx should be restarted. On a debian stretch with apache as webserver it works.
Server OS: Debian
Server OS version: Stretch
ISPConfig version: 3.1.11
nginx version: nginx/1.10.3
Not sure, but I think the problem is in
900-letsencrypt.inc.php in line 71 -
systemctl force-reload nginx does not work.
I had not tracked down what is realy send at this point but wouldn't be a
restart better for nginx?
