I can't get fingerprint

I can't get fingerprint.
Why is this happening?
The speed is too slow, even though I have authorized the IP.

@selenagomez2391 I tried authorizing on 2 IPs and got the result that:
On each IP, I can get 100 fingerprints every 3 minutes.
So, IP authorization cannot reach 1000 requests every 3 minutes.
It never happened before.
