Selfhosted

I'm trying to set up local DNS using Pi-hole.

I have successfully set up Pi-hole and added a local DNS record local.com, pointing it to the server running the Pi-hole container 192.168.0.101.

Then I set up the Audiobookshelf container using the guide from Audiobookshelf, where I set up Nginx Proxy Manager with the following compose file:

services:
  nginx-proxy-manager:
    image: docker.io/jc21/nginx-proxy-manager:latest
    container_name: nginx-proxy-manager
    ports:
      - 80:80
      - 443:443
      - 81:81
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
    restart: unless-stopped

And Audiobookshelf with the following compose file:

services:
  audiobookshelf:
    image: ghcr.io/advplyr/audiobookshelf:latest
    container_name: audiobookshelf
    volumes:
      - ./audiobooks:/audiobooks
      - ./podcasts:/podcasts
      - ./metadata:/metadata
      - ./config:/config
    restart: unless-stopped
networks:
  nginx:
    name: nginx-proxy-manager_default
    external: true

I did not specify a port, hoping that Nginx could manage it.

Then I set up Nginx Proxy Manager following the guide from Audiobookshelf by adding a proxy host. ~~Trying to resolve audiobookshelf.local.com to~~ I simply followed the guide and wasn’t sure why the “Forward Hostname / IP” should be the container name audiobookshelf.

I also created a self-signed certificate.

But I cannot access https://audiobookshelf.local.com/ or http://audiobookshelf.local.com/ (it automatically forwards to HTTPS).

I tried adding a local DNS record:
audiobookshelf.local.com → 192.168.0.101 in Pi-hole.
Now, when I access audiobookshelf.local.com, the site shows:
502 Bad Gateway – openresty

I think the problem lies in the Docker network setup. I suspect the Audiobookshelf Docker container is not communicating with Nginx.

Would appreciate any help!
