OpenV switch neutron error

Deployed open stack Rocky with hyper V. We are using OVS and flat network. Nova and neutron agents are up but Instance creation is failing with below error.

Error: Failed to perform requested operation on instance "win", the instance has an error status: Please try again later [Error: Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 8d262f0e-a851-4cd1-84c5-422e9d532fc2.].
