Nginx geoip does not show the country in the logs – Docker

I am using a public repo for nginx configured for geolocation with geoip, but I am getting dashes in the fields $geoip2_data_country_code $geoip2_data_country_name'. I have the following Dockerfile:

FROM alpine:3.11

COPY GeoLite2-Country.mmdb /usr/share/geoip/

STOPSIGNAL SIGTERM

CMD ["nginx", "-g", "daemon off;"]

And the two files nginx.conf:

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

load_module modules/ngx_http_geoip2_module.so; # GeoIP2

}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    # GeoIP2
    geoip2 /usr/share/geoip/GeoLite2-Country.mmdb {
        $geoip2_data_country_code source=$remote_addr country iso_code;
        $geoip2_data_country_name source=$remote_addr country names en;
    }

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '

                          '"$http_user_agent" "$http_x_forwarded_for" '
                          '$geoip2_data_country_code $geoip2_data_country_name';

    access_log  /var/log/nginx/access.log  main_geo; # GeoIP2

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

And nginx.vh.default.conf:

server {
    listen       80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

}

According to this page if I do docker run --rm -p 80:80 bubelov/nginx-alpine-geoip2 then I will get the correct log:

183.88.21.120 - - [16/Apr/2019:09:08:55 +0000] "GET / HTTP/1.1" 
200 612 "-" 
"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:66.0) Gecko/20100101 Firefox/66.0" "-" 
TH Thailand

But in my case it is the following:

192.168.3.1 - - [15/Jun/2022:10:46:11 +0000] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.0.0 Safari/537.36" "10.0.8.83" - -

The actual nginx configuration file is the following:
