Hi,

I followed the docs at https://www.elastic.co/guide/en/apm/agent/php/current/intro.html to attach the elastic-apm-php agent to my application and added the configurations to the php.ini file. When I run my application I get the following error:-

Elastic APM PHP Tracer [PID: 4790] 2021-01-07 13:10:22.365282+00:00 [ERROR] [Backend-Comm] [backend_comm.c:161] [sendEventsToApmServer] Sending events to APM Server failed. URL: `http://localhost:8200/intake/v2/events'. Error message: Couldn't connect to server.

The apm-server is reachable from the application instance, the trace data for java-agent is visible and I get the above error only for php-agent .

Kindly help me resolve this issue.

Thank You

Steps to reproduce:

1.Followed PHP agent docs.
2.restarted httpd
3.restarted apm-server

Hi @bimanarajesh - welcome back to the forums

Could please clarify if APM Server is running at localhost:8200 or a different address:port? If it is the latter did you configure server_url (for example by setting elastic_apm.server_url in php.ini)?

Hi @Sergey_Kleyman ,

The APM Server is running on a different IP address. The port 8200 and the server is accessible from the client instance.
Yes, I did set the elastic_apm.server_url in php.ini file.
