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.
