Here is what I set for fastcgi_param

fastcgi_param GEOIP_COUNTRY_NAME $geoip_city_country_name;
fastcgi_param GEOIP_COUNTRY_CODE $geoip_city_country_code3;
fastcgi_param GEOIP_REGION $geoip_region;
fastcgi_param GEOIP_CITY $geoip_city;

It was working few days ago but then GEOIP_REGION and GEOIP_CITY stopped working but GEOIP_COUNTRY_NAME and GEOIP_COUNTRY_CODE are working fine. Can anyone help?
