Sony TV can't access Jellyfin via official app, but it works via TV web browser - TaiZupan - 2025-08-13

I have an Orange Pi 5 running Ubuntu 24.04.1 LTS. I have Docker 28.3.3 installed. The static IP of the Orange Pi in my home network is 192.168.1.178.

I use docker-compose.yml file to deploy PiHole and Jellyfin services. They are exposed behind Caddy reverse proxy. I configured my router to use PiHole as the DNS server - IP 192.168.1.178.

I have the following docker-compose.yml file:

Code:
services:
  # reverse proxy for all services
  caddy:
    container_name: caddy
    image: caddy:2.10.0
    restart: unless-stopped
    ports:
      - "80:80"
    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile
      - caddy_data:/data
      - caddy_config:/config
    networks:
      - infra

  # DNS server (block ads, malware, etc.)
  pihole:
    container_name: pihole
    image: pihole/pihole:2025.07.1
    restart: unless-stopped
    expose:
      - 80 # web interface, accessed via Caddy
    ports:
      - "53:53/tcp" # DNS over TCP
      - "53:53/udp" # DNS over UDP
    environment:
      TZ: "Etc/UTC"
      FTLCONF_webserver_api_password: "SOME_RANDOM_PASSWORD"
      FTLCONF_dns_listeningMode: "SINGLE"
      FTLCONF_dns_interface: "eth0"
      FTLCONF_IPV6: "false"
      FTLCONF_dns_hosts: |
        192.168.1.178 pihole.lan
        192.168.1.178 jellyfin.lan
    volumes:
      - pihole_etc:/etc/pihole
      - pihole_dnsmasq:/etc/dnsmasq.d
    cap_add:

  # media server
  jellyfin:
    image: lscr.io/linuxserver/jellyfin:arm64v8-10.10.7ubu2404-ls73
    container_name: jellyfin
    restart: unless-stopped
    expose:
      - 8096 # web interface, accessed via Caddy
    environment:
      TZ: "Etc/UTC"
      PUID: 1000
      PGID: 1000
    volumes:
      - ./jellyfin:/config
      - /data:/data
    networks:
      - infra

networks:
  infra:
    enable_ipv6: false

volumes:
  pihole_etc:
  pihole_dnsmasq:
  caddy_data:
  caddy_config:

This is the content of the Caddyfile:

Code:
{
    auto_https off
    log {
        output file /var/log/caddy/access.log
        format console
    }
}

http://pihole.lan:80 {
    reverse_proxy pihole:80
    log
}

http://jellyfin.lan:80 {
    reverse_proxy jellyfin:8096
    log
}

I deploy the stack with "docker compose up -d" command.

Once the stack is successfully deployed, I can access http://jellyfin.lan/ from all my devices - PC, iPhone and iPad.

However, I have problems with accessing http://jellyfin.lan/ from my Sony KD65X85LAEP TV, which is running Android TV version 12, OS build is BRAVIA_VH22_M_EU-user 12 STT2.230505.001.S58 680921 release-keys. I use official Jellyfin application for Android TV. I verified that the TV's DNS resolver is listed as 192.168.1.178 (the IP of the Orange Pi). TV is connected to the network via ethernet. When I try to connect from the application, I get the following error when I enter http://jellyfin.lan/ as the server address:

Code:
Unable to connect to server, tried the following addresses:
https://jellyfin.lan - Unable to connect
https://jellyfin.lan:8096 - Unable to connect
https://jellyfin.lan:8920 - Unable to connect
http://jellyfin.lan - Unable to connect
http://jellyfin.lan:8096 - Unable to connect

When I inspect PiHole logs, I don't see any DNS queries from the TV towards the DNS server.

Interestingly, the problem only occurs in the official Jellyfin application for Android TV. If I use TV's web browser and navigate to http://jellyfin.lan/, it opens normally. I can see the DNS query in the PiHole console.

Bottom line: All devices on the local network can connect to Jellyfin on http://jellyfin.lan/. My Sony TV with Android TV can connect to Jellyfin using its built-in web browser. However, when I try to connect using the official Jellyfin application for Android TV, I get "Unable to connect" errors.

I tried unplugging the TV from electricity and plugging it in again. I also tried reconnecting the TV's Ethernet cable. Nothing helped so far. Does anybody have an idea why Jellyfin TV app can't connect to my Jellyfin server?
