Caddyv2 reverse proxy redirect issues

[MHunton]

I'm not sure if I have done something wrong as I'm quite new to caddy and selfhosting in general but when I load the login screen I get an error message saying "cannot connect to server", when I click login it redirects me and says "this page isn't working". Apologies if this is a simple issue and my own fault. Thanks in advance.

below is my docker compose and caddy v2 settings

version: "3"

services: server: image: yooooomi/your_spotify_server restart: always ports:

• "888:888" links:
• mongo depends_on:
• mongo environment: API_ENDPOINT: https://spotiserv.mydomain.com/oauth/spotify/callback # This MUST be included as a valid URL in the spotify dashb> CLIENT_ENDPOINT: https://spotify.mydomain.com SPOTIFY_PUBLIC: SPOTIFY_SECRET: mongo: container_name: mongo image: mongo:6 volumes:

• ./your_spotify_db:/data/db

  web: image: yooooomi/your_spotify_client restart: always ports:

• "3000:3000" environment: API_ENDPOINT: https://spotiserv.mydomain.com/oauth/spotify/callback

---

This is in my caddy file:

spotify.mydomain.com { reverse_proxy http://localhost:3000 }

spotiserv.mydomain.com { reverse_proxy http://localhost:888 }

Hello. You cannot change the inner port of the container. In the server, your ports definition should be 888:8080

Thank you so much, I knew it would be something I'd done wrong, I also realised I had my API URL entered wrong but I sorted that myself, it's working perfectly now!
