Hi @smart_admin1 ,

Can you describe your setup in more detail please ?

- what agent version is used ?
- what is the agent configuration ?
- what is the apm-server configuration ?
- does apm-server is hosted on Elastic cloud or self-hosted ? If self-hosted, do you use self-signed certificates ?

From the part of the stack trace that you provided, this looks like a certificate validation issue on the client (on Java agent side) that is unable to communicate with apm-server, but providing more details would be required for further investigation.
