When I execute the:

# neutron agent-list

I get the error:

neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
The server is currently unavailable. Please try again at a later time.<br /><br />



Neutron server returns request_ids: ['req-1900e1f9-c272-4bce-bf72-3bb15d16d942']

And I use the order:

openstack token issue

I got the information（I extract a fragment）:

| expires | 2017-06-01T04:43:19+0000

And now is 2017-06-01 UTC 11：52：00 +8000 （Beijing Time）

Why I can not neutron agent-list?
