check the ingress nginx controller and add host por as in the below format. $ kubectl get pod -n kube-system ingress-nginx-controller-789d9c4dc-5wnc2 -oyaml
To get the access via host ip , remove host FQDN name from the ingress config, leave empty or remove it.
The port set for metrodash-service inside ingress ist looking wrong to me.
