Seting up Nginx as Reverse Proxy

I’m tring to setup Nginx as Reverse Proxy and i follow this instructions: www.ipfire.org - Nginx

What I’m having trouble with is that I can’t get acme certificates because the script gives an error. It i try this script:

acme.sh --issue -d yourdomain_1.tld -w /usr/share/nginx/html

with my data i get this:

[root@ipfire .acme.sh]# ./acme.sh --issue -d test.domain.tld -w /usr/share/nginx/html --log

Can someone help me here?

Set Letsencrypt servers to default:

acme.sh --set-default-ca --server letsencrypt

…and try again.
