Kindly help regarding this.

Hi :slight_smile:

Do you have a Proxy Server with basic authentication in between or are you trying to authenticate with the apm server via a secret token?

Best,

Hi Felix

As I mentioned above that I have launched APM from elastic cloud like elastic search and Kibana. After that I have received APM Url and Secret Token. I have used APM Server URL wherever it required but I think, I have not used the secret token properly. Can you please guide regarding that.

And I have a doubt regarding APM Server i.e. If I am launching APM from elastic clound :-- Do i need to make any manual configuration to run APM server properly.

Thanks in Advance.

Ah, got it. This is the configuration for the secret token: https://www.elastic.co/guide/en/apm/agent/java/current/config-reporter.html#config-secret-token

You can find your secret token in the APM tab of your cloud deployment.
