Hi,

Others have experienced a similar error(like [here](https://discuss.elastic.co/t/apm-java-agent-exception-at-startup/250208)) and the solution was that the error is not an error and will be demoted to a debug message in later releases.

The real error seems to be this:

Did you have a look in the logs on the APM server?  
Do you have a firewall in between(although you already said that the agent can connect for healthchecks)?
