Difference between .pem and .crt and how to use them

I changed the template it uses to point at the SL certs I have already created.

SSLVerifyClient none
    ssl_certificate /etc/letsencrypt/live/%domain%/fullchain.pem; # ma>
    ssl_certificate_key /etc/letsencrypt/live/%domain%/privkey.pem; # >
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

Which looked fine,

It looks like you're combining nginx with Apache configurations? To me, it doesn't look "fine".

Error: Certificate Authority not found

Interestingly this error message cannot be found in the Hestia source code
