Not sure if an intermittent glitch, but doing an order for a customer in their account (pay via phone, select cash as method and put through) once logged in it showed the forbidden access screen. I tried my test account and the same thing for that also. Though it was 2 hours after abuseipdb daily limit exhausted. Though doing the same process just now, it is fine. I am guessing it may be AbuseIPDB service may do this due to exhausted access?
I also tried after exhaustion on mobile data, and the same forbidden once logging in. But not logging, it seemed okay.
