ceilometer not upgrade due error 401 authentication - devstack

Question

I installed openstack using devstack in one node. And this is my local.conf file:
[[local|localrc]]
ADMIN_PASSWORD=StrongAdminSecret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
PUBLIC_INTERFACE=enp0s8
HOST_IP=192.168.1.104
FLOATING_RANGE=192.168.1.0/24
PUBLIC_NETWORK_GATEWAY="192.168.1.1"
Q_FLOATING_ALLOCATION_POOL=start=192.168.1.120,end=192.168.1.140
enable_plugin gnocchi https://github.com/openstack/gnocchi master
enable_service gnocchi-api,gnocchi-metricd,gnocchi-grafana
enable_plugin ceilometer https://git.openstack.org/openstack/ceilometer.git
CEILOMETER_BACKEND=gnocchi
enable_service horizon
enable_plugin cloudkitty https://git.openstack.org/openstack/cloudkitty.git master
enable_service ck-api ck-proc
CLOUDKITTY_COLLECTOR=gnocchi
Then try to install gnocchi and ceilometer from this link:
https://dommgifer.gitbook.io/knowledge/openstack/ceilometer-and-gnocchi-install
gnocchi upgrade is OK but when upgrade ceilometer this error is occurred:
keystoneauth1.exceptions.http.Unauthorized: The request you have made requires authentication. (HTTP 401) (Request-ID: req-dd1d31cf-f0ae-4c92-a03b-a36b08139b53)
