Hi and welcome to our forum 👋 > [@kama99](#): > > Also i'm thinking about apm server certificate, should I add it somewhere? Since you are using HTTP to communicate with the APM Server, it shouldn't be related to SSL/TLS. Most likely the APM Server is not reachable at `http://localhost:8200` from your application host. Try `curl` to verify it is accessible from where the agent is deployed first. Also, check out our [troubleshooting guide](https://www.elastic.co/guide/en/apm/agent/java/current/trouble-shooting.html#trouble-shooting-no-data). > [@kama99](#): > > I have spring boot project with apm-agent dependency If you did add the agent as a dependency, then you should remove it. If you added the [`apm-agent-attach`](https://www.elastic.co/guide/en/apm/agent/java/current/setup-attach-api.html) as a dependency, then that's OK. Make sure to go over our [setup](https://www.elastic.co/guide/en/apm/agent/java/current/setup.html) guide and the rest of the agent documentation. I hope you can find most answers there, let us know if not. ---
