Thank you so much @stephenb , that is a good catch!

Now my error becomes

> {"level":"debug","time":"2021-08-08T17:00:09Z","message":"request failed: sending event request failed: Post "[https://hm-apm-apm-http.elastic:8200/intake/v2/events\](https://hm-apm-apm-http.elastic:8200/intake/v2/events%5C)": x509: certificate signed by unknown authority (next request in ~36s)"}

As this is a self signed certificate, I found this answer: [X509: certificate signed by unknown authority - #2 by jsoriano](https://discuss.elastic.co/t/x509-certificate-signed-by-unknown-authority/156815/2)

As I am using Elastic Cloud on Kubernetes (ECK) way to install, I am not sure how to change the config.

I also tried to change to

```auto
ELASTIC_APM_VERIFY_SERVER_CERT: "false"

```

for my Go app. However, just like [the doc](https://www.elastic.co/guide/en/apm/agent/go/current/configuration.html#config-verify-server-cert) says, if I am using `ELASTIC_APM_SERVER_CERT`, the `ELASTIC_APM_VERIFY_SERVER_CERT` will be ignored.

Any guide? Thanks!
