Hello,

I currently have OpenStack manually deployed by following the official install documentation, but I have faced a weird situation. When I send an api request to placement api service using the following command:

curl -H "X-Auth-Token: $T" http://controller:8778

I received a status code of "200", which indicates a successful operation. But, when I issue the following request:

curl -H "X-Auth-Token: $T" http://controller:8778/resource_providers

I received a status code of "503", and when I checked the logs of placement and keystone, they say that the authentication failed. For the same reason, nova-compute can't register itself as a resource provider.

I'm sure that the authentication credentials for placement are set properly, but I don't know what's the problem.

Any suggestions, please?
