Is there anything special in your setup? For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc.

It's a very straightforward set up. We just run a node server on an on-premise ubuntu 16.04 box.

Description of the problem including expected versus actual behavior. Please include screenshots (if relevant):

Basically, our server is failing to talk to APM in any capacity. One-off scripts on the same box and node version work fine.

Steps to reproduce:

  1. Boot up our server using pm2. Initialize agent.

Errors in browser console (if relevant):

Provide logs and/or server output (if relevant):

The Node.js agent doesn't currently support custom certs. How are you trying to use it currently?
