I have a java application and want to monitor it. the two hosts between the APM server and the application server are well connected. I have also deactivated the firewall but the data from the apm agent was not successfully sent to elasticsearch and did not appear in kibana

**Kibana version** : 8.1.0

**Elasticsearch version** : 8.1.0

**APM Server version** : 8.1.0

**APM Agent language and version** : JAVA version 1.35.0

**Log from APM-Server** :

```auto
{"log.level":"error","@timestamp":"2023-01-19T03:21:45.919-0500","log.logger":"beater","log.origin":{"file.name":"beater/waitready.go","file.line":64},"message":"precondition failed: EOF","service.name":"apm-server","ecs.version":"1.6.0"}
{"log.level":"error","@timestamp":"2023-01-19T03:22:00.930-0500","log.logger":"beater","log.origin":{"file.name":"beater/waitready.go","file.line":64},"message":"precondition failed: EOF","service.name":"apm-server","ecs.version":"1.6.0"}

```

**Log from Catalina.out** :

```auto
2023-01-19 15:38:03,543 [elastic-apm-server-reporter] WARN co.elastic.apm.agent.report.IntakeV2ReportingEventHandler - null
2023-01-19 15:38:03,543 [elastic-apm-server-reporter] INFO co.elastic.apm.agent.report.IntakeV2ReportingEventHandler - Backing off for 36 seconds (+/-10%)

```

**Configuration in Catalina.sh**

```auto
export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/opt/Elastic/elastic-apm.jar -Delastic.apm.service_name=supercar -Delastic.apm.server_urls=http://172.16.11.226:8200 -Delastic.apm.environment=production -Delastic.apm.application_packages=org.apache.org"

```

**And here if i curl from application server to APM Server**

Hi @zerratriani ,

Could you capture the logs using [this procedure](https://www.elastic.co/guide/en/apm/agent/java/current/trouble-shooting.html#trouble-shooting-logging-procedure) please ?

For now only the agent logs are required for investigation.

This part of the APM Server logs indicates that something is not right with the setup for the apm-server, as it cannot verify that the index templates are properly setup.

Please provide more details how you set up the APM Server (standalone or managed by Elastic Agent & Fleet) and if you have changed Elasticsearch output configurations in the APM Server.
