Hi, I've been using Let's Encrypt for 4 of my websites and it works just fine. But it's not working for my last one. I've checked the SSL function and it works but when i check the Let'Encrypt function, i wait for a few second for the task to end and when i verify the function is no more checked. I don't understand why this particular website can't have its let's encrypt certificate... The DNS are OK ans pointing to the good IP address. Where should i watch for the error logs ? I run ISPConfig 3.1.6 under Ubuntu 16.04 server and i have followed the tutorial : https://www.howtoforge.com/tutorial/perfect-server-ubuntu-with-nginx-and-ispconfig-3/ ... So i run Nginx, not Apache. Thanx in advance for your advices.
