The plugin cannot just stop working after some time. Either the code implementation has been messed up or if you are using the free ip-api maybe you have surpassed the 150 req/min. Anyway, it is hard to say what happened just from your comment.
plugin working on other domain fine. But on first domain in that i install plugin not working, I have try with all plugin versions of AICP but no one working. I remove plugin remove database table and refresh install but again not working. Can you mention the fix here?
It seems like there is some kind of plugin conflict in your first domain which I just cannot say what is what from here.
