This page isn’t working: localhost didn’t send any data.

I've tried adding a dash app to /app/dash. I've verified that it runs as expected when I do python3 app/dash/K562.py, when I import default dash rather than from .dash import Dash

When I build and run the container, the logs are clean:

$ docker logs -f flask-dash-app_web_1
 * Serving Flask app 'app/main' (lazy loading)
 * Environment: development
 * Debug mode: on

However, I'm unable to load the page:

Where might I be able to find logs inside the container which suggest where the error is?
