Take a look at [this](https://www.elastic.co/guide/en/cloud-on-k8s/1.0/k8s-apm-server.html#k8s-apm-secret-token). The specified command should get you the secret token. Make sure it is Base-64-encoded and stored in the right field. Then make sure the agent actually uses the right token (or retrieves it from the right secret, if using the approach suggested in the blog post). ---

Thanks @Eyal_Koren kubectl get secret/apm-server-quickstart-apm-token -o go-template='{{index .data "secret-token" | base64decode}}' -n elastic-system output: elasticuser -Delastic.apm.secret\_token=elasticuser apm-server-quickstart-apm-token and elastic.apm.secret\_token are elasticuser, yet i am getting authentication issue. ---

Did you configure the [APM server](https://www.elastic.co/guide/en/apm/server/current/secure-communication-agents.html#secret-token) to use the same token as well? ---

Did you set that secret value _after_ creating the ApmServer resource? If so, I suspect you're hitting [https://github.com/elastic/cloud-on-k8s/issues/523](https://github.com/elastic/cloud-on-k8s/issues/523). Until that's addressed, if you delete the apm-server pod then the new one should pick up the updated secret token. ---
