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

I've set Elasticsearch, Logstash, and Kibana on my AWS EC2 server. In addition, I've installed flask APM version 4.2 and APM 6.4.2 on my application server. However, when I launch my flask server, I've got an error which is that 'localhost:8200' page not found. (404) How can I resolve this problem?

**Steps to reproduce** :

1. Install ELK on ec2 server.
2. Install Flask APM agent and APM server on my application server (It is also ec2)
3. Launch the server code.

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

Hi and thanks for reaching out 🙂  
Please note that Python agent of versions 4+ is only compatible with APM Server 6.5+ . (see more in [the Python agent's documentation](https://www.elastic.co/guide/en/apm/agent/python/current/upgrading-4.x.html)).
