These messages indicate you've hit the limits for likes, follows, or unfollows from your Instagram account.
Instagram tells us when to slow down and we already know approximately what the limits are. We stay under those limits and respect whenever it tells us to back off, just like a human would when using the Instagram app.
Usually this problem will clear up on its own within a few days to a week.
