https://http.cat/ error pages for nginx

Nginx.conf

Set resolver for nginx, you probably already have one if you use SSL OCSP stapling 8.8.8.8 are Google's public IPv4 DNS servers.

resolver 8.8.8.8 valid=86400;
resolver_timeout 10;

Error pages

Place this configuration on your server_block or create some .conf file on /etc/nginx and use include to call it, like you would with global SSL configuration.
