RabbitLoader servers connect to your origin hosting server to optimize webpages and boost the website loading speed and improve Core Web Vitals. There are some known services such as Cloudflare, Imperva, Sucuri Web Firewall, Wordfence Security, etc which can prevent such connection attempts made to the origin restricting RabbitLoader services.
While such software is intended to block bad traffic and bots, they can block even good bots if the IP addresses are unknown to their system. To avoid such issues, RabbitLoader recommends getting our IPs whitelisted.
