Blocking Countries

To block visitors from a specific country, or multiple countries, create or upload a file to wp-content named .nginx-block-country. This happens on the server level and is more effective than a plugin, plus the visitor does not get to the site to take up any resources.

The file:

map $geoip2_data_country_code $block_country {
    default 0;
    CN 1;
    VN 1;
}

To add a country, add the 2-character ISO code, followed with 1 and semicolon, for example, for China use CN 1;. In the example code above, we've added China and Vietnam.

Go to the WP-CLI tab and click on Restart Workers in the toolbar to clear the cache.
