This pop-up message comes directly from Instagram. It is not related to the app. The main reason for your situation is about: using an overloaded server and (or) running activities too fast.

For this issue, you can solve this problem by:

– Sign-in on Instagram’s website:
. If your account has been unlocked all you need to do is resign-in our application.
. In the worst case, Instagram will ask you to change your password, then you need to finish this step and resign-in our application.

– Or the safest way is to be patient, Instagram itself will unblock you after a while.

Overloaded servers are one of the most common issues you can encounter when using any apps like Followers+ Track for IG. Thank you so much for understanding.
