I’m trying to add in graylog into a docker-compose config, and while I can get the server in and the UI to show up, it throws an error on the page that “We are experiencing problems connecting to the Graylog server running on [http]://172.18.0.8:9000/api/. Please verify that the server is healthy and working correctly.” The flow of the application is:

1. Namecheap DNS (dynamic, updating with ddclient)
2. xFinity modem in bridge mode
3. Netgear router with port forwarding of 80 and 443 to server
4. server with docker-compose running - fronted by ‘jwilder/nginx-proxy’ with the SSL companion ‘JrCs/docker-letsencrypt-nginx-proxy-companion’ as well, routing via ‘host’ name to this server

Net traffic seems to work fine in general (forwarding rules, etc are configured correctly). I can get the GrayLog webpage to load, and my other docker images load fine as well.

docker-compose (.env file has URLBASE value):

```
version: '2'

```

The long way around this is I would expect to get the webUI making requests back to ‘[https://logs](https://logs).{URL}/api/’ - but it’s not. It is making requests to ‘http://{the internal IP of the container}:9000/api/’ and I don’t understand why that is.

I can see from chrome Dev tools that the config.js call returns:

```
window.appConfig = {
  gl2ServerUrl: 'http://172.18.0.8:9000/api/',
  gl2AppPathPrefix: '',
  rootTimeZone: 'UTC',
};

```

Any help is much appreciated!

One quick note - if on that page i then run in console an override to what i expect the gl2serverurl value to be (the real URL), then it works and I can login and search logs as expected.
