GRPC sanity tests fail on minikube / openshift

GRPC sanity tests fail on minikube with the below error on the client side

Posting a new experiment...
Adding new experiment: petclinic-sample-2-75884c5549-npvgd
Error: An error occurred executing command: failed to connect to all addresses
Post new experiment failed!

From the service log:

2022-07-15 09:12:26 - INFO - hpo-service - Starting HPO service
2022-07-15 09:12:26 - INFO - rest_service - Access server at http://localhost:8085
2022-07-15 09:12:26 - INFO - grpc_service - Starting gRPC server at http://0.0.0.0:50051

I have exported HPO_HOST & PORT to minikube IP & port no. of HPO service. Not sure if I 'm missing out anything here or if any
changes are required to grpc service.

Shouldn't the IP & port no. in the INFO statements in service log display the cluster IP and Port?
