Imperva is a cyber security software and services company. Many web hosting services or individual website owners use Imperva to protect their servers again attacks and data breach attempts. Earlier Incapsula used to be a separate product that is now part of Imperva.
Due to the nature of firewall applications, Incapsula (now Imperva) can block even RabbitLoader servers to connect to your origin for website optimization and speed improvements.
To make things work, you can request your hosting service provider to whitelist RabbitLoader’s IP address from Incapsula. Once this is done, our servers can communicate with your servers without any issue.
