GrowthBook Users

Hey folks, I’m trying to get started with Growthbook - installing on a dev server for testing/evaluation purposes but I’m getting stuck. I made these changes to `docker-compose.yml`
```ports:
  - "4000:3000"
  - "4100:3100"
depends_on:
  - mongo
environment:
  - MONGODB_URI=<mongodb://root:password@mongo:27017/growthbook?authSource=admin>
  - APP_ORIGIN=https://<dobdomin.domain.com>:4000
  - API_HOST=https://<dobdomin.domain.com>:4100
  - JWT_SECRET=&lt;secret&gt;
  - ENCRYPTION_KEY=&lt;key&gt;```
And created a simple proxy config on nginx. Nothing fancy, but I keep getting this error:
```Error connecting to the GrowthBook API at https://<dobdomin.domain.com>:4100.

Received the following error message:

Load failed```
What am I missing?

Hi Wagner - typically you get that error because of using internal urls

the API_HOST url must be the url that the application running in your browser can use to request data from the API.

so, you should be able to visit the API_HOST url in your browser, and if it’s working, you’ll see a JSON object returned

the APP_ORIGIN is used for CORS headers, and should match the URL of the app as seen from the API
