I am really new to this. I will appreciate if anyone can help on how to block country level access via NGINX.

You can use Nginx’s http_geoip_module to restrict access from a specific geo-location or country to your website. You can check the following article:
Another thing is using iptables to block the traffic before reaching Nginx at all. I found this guide that should be helpful. This references blocking Chinese IPs and the script near the bottom uses a third-party service to source the IP lists.
Hope that this helps!
I’m not sure Nginx is the right place for this block. This is more of a firewall thing. As such, I’ll suggest adding the country block level on your firewall.
I’ve used CSF for such measures and I can confirm it works properly. In order to block a country you can use the
CC_DENYoption which accept two-letter country codes such as US, GB and etc.
In order to list more than one country you just need to separate them using comas:
CC_DENY = "AB,CD,EF"
You may find a list of ISO 3166-1 alpha-2 codes at https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
If you’re not familiar with CSF or you want to install it on CentOS or Ubuntu droplet check out this mini tutorial:
