blocked browser integrity check

Good Morning. I’m having blocking issues with my PagSeguro notification API. Sometimes the cloudflare firewall blocks PagSeguro’s communication, sometimes it doesn’t. When there is a blockage, PagSeguro tries other times until it succeeds, but this has caused a delay in the release of the order. I have already removed the security from the URL of my file that receives the notification from PaSeguro and also released the list of IPS from PagSeguro in PagRules, but even so some communication attempts are being blocked in the integrity check of the browser (Jakarta Commons-HttpClient / 3.1 ). What should I do?
