Letsencrypt on Ubuntu 16.04/Nginx

Posted on April 13, 2017

I tried following the tutorial below but when I go to check the connection via SSL Labs, I get Assessment failed: Unable to connect to the server. SSL Labs suggests this is a common error due to firewall settings.

My firewall settings are:

To                         Action      From
--                         ------      ----
22                         LIMIT       Anywhere                  
443                        ALLOW       Anywhere                  
80                         ALLOW       Anywhere                  
22 (v6)                    LIMIT       Anywhere (v6)             
443 (v6)                   ALLOW       Anywhere (v6)             
80 (v6)                    ALLOW       Anywhere (v6)

So after editing the digitalocean file, it is now working. However, I have no idea when or why I created this file.

Hi @chrisburton But when you visit your domain through a browser, do you get any errors? Have a look at the error log too in /var/log/nginx/error.log

Okay, Nginx is not listening on port 443, which likely means you have not created server block configuration for https - or you have not activated it.

Do you have a https-configuration in /etc/nginx/site-enabled ?

You are welcome to post your configuration.
