Followliker: login_required was requested from instagram

Hey guys getting this error code

"last response code: 400 ->login_required was requested from instagram"

How do i fix it?

Did you check your Instagram account? I mean maybe there were any pop-ups where you have to identify yourself or something..
On the whole followliker is not the best service for promotion. Hope you'll solve the issue but my advice is to choose something else with a wider complex of offers and what is more stable.
