TIP 2: Check out the [troubleshooting guide](https://www.elastic.co/guide/en/apm/get-started/current/troubleshooting.html) first. Not only will it help you to resolve common problems faster but it also explains in more detail which information we need before we can properly help you. **Kibana version** : 8.4.1 **Elasticsearch version** : 8.4.1 **APM Server version** : 8.4.2 **APM Agent language and version** : PHP **Browser version** : **Original install method (e.g. download page, yum, deb, from source, etc.) and version**: **Fresh install or upgraded from other version?** Fresh **Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs?

Hi Pragadeeswar Padmanaban, Could you check the following if the issue is still active: - Is the url valid? - Did you set the secret\_token properly? - Is there a firewall active? Port 8200 might be blocked internally Greetings, ---

Hello Peter, I have the same problem, here's some more info : - The url is valid and the 8200 port is open : I can curl my apm-server from my php server and get a response. - When the error occurs, there is nothing appearing in my apm-server's logs - I tried with 2 different apm-servers, one on a remote server with an API-key and one on a localhost apm-server with no API-key - Both apm servers already work with the java apm agent ---

Can you check the php\_info(); contents to see if the url and secret\_token is filled in? ---

Thank you for your quick reply ! I finally managed to retrieve some data. The connection problem is due to SELinux blocking the connection. A quick workaround is to use `setenforce 0` Sadly, we can't use this workaround in production for obvious reasons, but now we know it's not a configuration problem.
