Which IP/Domain name should Firewall allow to get WDATP Definitions update for Linux

Hi I'm currently using Windows Defender ATP for Linux on a Linux Redhat server and got a problem with the definitions update as it couldn't update, always return "update_failed" result. Since this server is connect through a static proxy from our company which I have configured follow the installation document, I suspected it need to allow an IP or domain to connect with the update server. But I need to know which specific domain or IP (which can obtain through nslookup command) I needed so I can request my IT department to allow access to it
