For people finding this: There was an issue in my AWS security groups. The cluser directly connected to the pods and I had a firewall blocking 8080 (nginx-proxy grafana port). Also, by default, grafana & prometheus nginx config do not bind on an IPv6 address: https://github.com/rancher/charts/blob/dev-v2.10/charts/rancher-monitoring/105.1.0%2Bup61.3.2/charts/grafana/templates/nginx-config.yaml#L34. You can add [:]8080 & [:]8081 to the nginx configMaps to make them bind to IPv6 ports as well.
