Not able to create a SSL Cert using the built in Let's Encrypt service

Every time I try and create a cert using the Let's Encrypt service in the Fortigate it fails. I have followed the KB's I have found and also tried through the CLI. I enabled DDNS, but no matter what I do, it just fails. The Fortigate is a 300E running 7.0.5. Is there anything special that has to done. 

Here is what I using and doing. I have called Fortinet support, but the person I spoke to ran into the same situation. 

(Yellow Highlighted area: Yeah, not so much)

It used to generate logs, not sure why its not now.
