Bug Description

Openstack version - pike Installation process - multinode kolla

I am observing an error as Unable to establish connection to http://controller:8774/v2.1/flavors/detail. Also, it gives error as " keystoneauth1.exceptions.connection.ConnectFailure" However, this error is not regular and that is why I am not finding an exact solution. Can anybody help what can be the issue?

I tried changing the timeout values but still observing the errors.

Please find the log details below-

This isn't a bug in keystoneauth, it's just saying it can't connect to nova. Check that nova is running and check the nova-api logs for errors.

Changed in keystoneauth:
status:	New → Invalid
