SETUP (nothing new here, it's from the docs)
On another server you control:
$ git clone https://github.com/letsencrypt/letsencrypt
$ cd letsencrypt
$ ./letsencrypt-auto
- Make sure your server listening on port 80 and 443 is open (you can pick specific one using these instrucitons: https://letsencrypt.readthedocs.org/en/latest/using.html#standalone)
- DNS for url needs point to this server which is NOT your modulus server
- Make sure your server has open outbound ports
##Generate SSL Cert:##
$ ./letsencrypt-auto certonly --standalone -d EXAMPLE.COM
- Point DNS to modulus http://help.modulus.io/customer/en_us/portal/articles/1700863-custom-domains?b_id=9670 54.236.216.66 and 107.21.216.112 or aws-us-east-1a.onmodulus.net
