From James's Wiki
The Certbot from the repos is old...there was some security issue that froced them to shut down something that the old version uses to create security certificates so it doen't work anymore. the following instructions works around all that.
How to install and run the latest version of Certbot:
wget https://dl.eff.org/certbot-auto
chmod a+x ./certbot-auto
./certbot-auto
Note: if you get an error run it again. verified working on 4/29/18
