Adsense doesn't show all of a sudden

When i use a proxy it works, also when i modify domain to choose different country like or it works well. In my country it doesn’t work when using What can i do to go back to normal. Something else i noticed is on the adsense dashboard >>Top countries to click is pakistan but main traffic is from kenya. Only single click from pakistan. Anybody who can help
