@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.
I can get fingerprint using “PerfectCanvas request” now but it's very slow. It usually takes several minutes to get fingerprint if using “PerfectCanvas request”
