I have my project on GKE and I installed Grafana for getting metrics. After upgrading K8s version to 1.6.2 Grafana stopped to works. I can't see cluster and pods metrics on the dashboard. I can't also see namespaces that I have already set. If I try to access to influxdb via http ( https://X.X.X.X/api/v1/proxy/namespaces/kube-system/services/monitoring-influxdb:http/) I got this error Error: 'ssh: rejected: connect failed (Connection refused)' Trying to reach: 'http://10.0.7.3:8083/'. So, if you need some other information, please ask me. Thanks.
