You need to fill in the ip of the calling endpoint on the access management page of the console (https://www.thesports.com/zh/user/ips) to call the endpoint.

Why does calling the endpoint after filling in the IP still return "IP Unauthorized"?

Indicates that the IP of the calling endpoint is inconsistent with the IP entered in the console. You can check whether the filled in IP is the final IP of the calling endpoint. What is needed is the export IP, not the local IP. You can also confirm whether the export IP is in the form of an IP pool, causing the export IP to be inconsistent every time.

Can it support the form of ip pool?

not support. Currently, the endpoint only supports fixed IP calls.
