Do you have "controller" as a valid host in your environment?

Is this devstack or are you running keystone separately?

[Ngo Tuan Hien (ngotuanhien)]

Thank you for your respond!
It turns out to the problem of V2 and v3 of the Identity service of my keystone.
The bootstrap admin port configuration in the guide is incorrect (https://docs.openstack.org/keystone/pike/install/keystone-install-rdo.html#install-and-configure-components). We are no longer use port 35357 in V3.
