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
--                         ------      ----
