Can’t get geoIP to work

Hi, great plugin, thanks!

I’m trying it out and I setup the geoIP.
Not sure if there are any requirements but it just doesn’t seem to work for me.
I have set to show AUD by default and Yen if in Japan.
When I go to the GeoIP settings it says I’m in the US although I’m in Argentina. I used https://whatismyipaddress.com/es/mi-ip and it says I’m in Argentina.
When using a proxy to be in Tokyo, GeoIP settings say I’m in the US too, and prices show in AUD instead of Yen. When going to https://whatismyipaddress.com/es/mi-ip says I’m in Japan so proxy works fine.
Am I missing something?
