Hey guys!
1. The problem I’m having:
I own a domain with the following CNAMEs:
Because I have a dynamic IP at the server location I point my domain to DuckDNS which gets updated by a (the offical I guess) DuckDNS container.
Jellyfin as well as Caddy also run in a container on my server.
I can connect to my jellyfin instance remotely via Browser, via IOS. Outside and inside of my network.
But I cannot connect to Jellyfin remotely via Android or AndroidTV. I can only connect to Android devices when I’m inside my network with the local ip (http://192.168.178.31:8096/)
2. Error messages and/or full log output:

3. Caddy version:
v2.7.6
4. How I installed and ran Caddy:
I followed the offical docker installation, this is my docker-compose.yml
GNU nano 6.2 docker-compose.yml
version: "3.9"
services:
caddy:
image: caddy:latest
restart: unless-stopped
ports:
- "80:80"
- "443:443"
- "443:443/udp"
volumes:
- ./Caddyfile:/etc/caddy/Caddyfile
- ./site:/srv
- caddy_data:/data
- caddy_config:/config
networks:
- caddy
volumes:
caddy_data:
caddy_config:
networks:
caddy:
external: true
a. System environment:
I run proxmox where this server runs as a VM with ubuntu 22.04.
b. My complete Caddy config:
This is my Caddyfile:
{
email admin@notReallyMySite.com
}
portainer.notReallyMySite.com{
reverse_proxy portainer:9000
}
git.notReallyMySite.com {
reverse_proxy gitea:3000
}
cloud.notReallyMySite.com {
reverse_proxy nextcloud-nextcloud-app-1:80
}
video.notReallyMySite.com {
reverse_proxy invidious-invidious-1:3000
}
immich.notReallyMySite.com{
reverse_proxy immich_server:3001
}
search.notReallyMySite.com {
reverse_proxy searxng:8090
}
jellyfin.notReallyMySite.com {
reverse_proxy jellyfin:8096
}
I changed my Domain name and my public ip as I don’t feel comfortable sharing it 
I hope thats ok even tho it mentioned that it isn’t.
Thanks in advance for taking your time and helping me, really appreciate it!
Where would i change set path? I’m using linuxserver jellyfin:latest and basically didn’t change any default settings.
