Geo redirect based on ip in different countries not supported in wpmu??

I tried to use lite version of country code to redirect users based on their country locations.
Currently I’m using wordpress wpmu platform with subdomains, I set australian visitors being redirected to https://au.handyloft.com, while others remains https://handyloft.com, but it seems there is a loop there, I see the address being redirected to https://au.handyloft.com, but when it’s redirected to au.handyloft.com, it’s redirected again to au.handyloft.com, so keep being redirected.
Basically, I only want my homepage https://handyloft.com to be redirected by country, is there any solution to this?
