How to install it with Traefik?

[Daniel199438]

I have tried it several times, but I didnt get it to work. I always get a '502 Bad gateway' error.

Thats the modified docker-compose.prod.yml file:

version: '3'
services:
  api_server:
    image: danswer/danswer-backend:latest

      echo \"Starting Danswer Api Server\" &&
