We are using kibana 7.7 and co.elastic.apm:apm-agent-attach:1.21.0 and getting error soon after apm server starts. It makes our services visible in kibana, but anyway it logs such errors every 5 minutes:
[elastic-apm-remote-config-poller] ERROR co.elastic.apm.agent.configuration.ApmServerConfigurationSource - Read timed out
In config we use only 3 properties and they all configured correctly:
service_name=... application_packages=... server_url=...
Maybe someone knows what is the problem? Or at least how to disable this errors logging, we do not want to read any remote config from server in our app.
