502 error with Caddy and Mealie

[poperigby]

Hey, I'm having a bit of trouble with Mealie and Caddy. This is my Docker Compose file:

services:
  mealie:
    container_name: mealie
    hostname: mealie
    image: hkotel/mealie:latest
    environment:
      TZ: America/Los_Angeles
      RECIPE_PUBLIC: 'true'
      RECIPE_SHOW_NUTRITION: 'true'
      RECIPE_SHOW_ASSETS: 'true'
      RECIPE_LANDSCAPE_VIEW: 'true'
      RECIPE_DISABLE_COMMENTS: 'false'
      RECIPE_DISABLE_AMOUNT: 'false'
    volumes:
      - data:/app/data
    restart: always
volumes:
  data:
networks:
  default:
    name: reverse_proxy
    external: true

reverse_proxy is an external network that both Mealie and Caddy are connected to.

This is the relevant part of my Caddyfile:

food.haddock.cc { # Mealie
    import auth
    reverse_proxy mealie:9925
}

When I navigate to https://food.haddock.cc, I just a get 502 bad gateway error, and this shows up in my Caddy log:

I have the exact same issue. Did you find a solution?

[poperigby]

I'm sorry. I don't remember how I fixed it, and I started using podman recently.

The mealie API runs on port 9000. You will need to change it on this line:

reverse_proxy mealie:9925

Port 9925 is just the example used here.
