Grafana Configuration

Hi Guys .
Hope you are doing well , iam relatively new to grafana , i have a oauth2-proxy deployment running on k8’s which iam try to use as a method of authentication with Google as Auth Provider for Grafana worklod which is behind nginx-ingress controller , now i kind of worked it out at a stage where iam able to authenticate with a google account when i open grafana URL but after authentication instead of signing me in to Grafana it comes back to the Grafana login form again ?

Could anyone help me here in setting me right config at grafana/nginx ingress side ? Thanks

what error are you seeing? Is this a new issue and are you running 8.3.5+. There was a change to how Grafana handles host headers in 8.3.5
