How to create a customer for domain cluster

Hi!,’m trying to create a customer for my keycloak cluster,Since I can only access it through a remote machine,so I want to use add-user-keycloak script, when i use command:
./add-user-keycloak -u <> -p <> --domain,but I went to visit ‘http://ip:port/auth’。
The page prompts me that I still need access ‘http://localhost:8080/auth’ to initial admin user

HI, did you solved this? I have the same issue…
