IP Addresses are not correctly relayed on DigitalOcean

[komninoschatzipapas]

We have deployed this proxy on a DigitalOcean app as follows (using the one-click install on the Readme of this project):

ingress:
  rules:
  - component:
      name: mixpanel-api-proxy
    match:
      path:
        prefix: /api/t
services:
- dockerfile_path: ./Dockerfile
  git:
    branch: master
    repo_clone_url: https://github.com/mixpanel/tracking-proxy.git
  http_port: 80
  instance_count: 1
  instance_size_slug: apps-s-1vcpu-1gb
  name: mixpanel-api-proxy

Unfortunately, our events on Mixpanel now show with Country and City as (not set). We have double checked to ensure IP tracking is enabled on our Mixpanel.js setup.

If this helps, we know that DigitalOcean sends the end user's IP as the do-connecting-ip header on requests through the App platform.
