Kiali with Grafana Integration NOT working w/ auth

The Kiali with Grafana is not working with authentication w/ below configuration. There is no error in kiali pod but Kiali dashboard says “unknown error from Grafana (400)”. Because of this error I’m not able to see Grafana link in Kiali dashboard.
