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, 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.
You may ask your hosting service to whitelist the below IPs-
188.8.131.52, 184.108.40.206 and 220.127.116.11RabbitLoader IPs to be whitelisted
Ports: Most of our users need to set any specific port because RabbitLoader uses standard ports – 80 and 443.
Whitelisting or Allowlisting depends on the services you use. Below are instructions for a few services, if your hosting company is missing here, you can contact their support team to do it for you.
