Can't access Vaultwarden

I'm trying to host a vaultwarden instance through docker and failing miserably. This isn't my first attempt either but I've got much further than before.

I'm using a DuckDNS domain with caddy as reverse proxy, but it appears that the domain is defaulting to port 80 no matter how I set up the config. I can't specify a port number in DuckDNS as far as I can tell. If the simple solution is to just buy a domain name I will consider it. Otherwise could really use some help in sorting out why it's not connecting.

I can't access Vaultwarden on the internal IP as it's not being served as SSL but both Vaultwarden and Caddy are running with no errors in logs. I've left out a bunch of admin env variables for the Vaultwarden service to truncate the code.

docker-compose:

`[___](services:

vaultwarden:

        container_name: vaultwarden

    image: vaultwarden/server:latest

    restart: unless-stopped

    ports:

      - 11808:80

      - 11443:443

    volumes:

      - ./data/:/data/

    environment:

      - ROCKET_PORT=11444



  

caddy:

        image: caddy:2

    container_name: caddy2

    restart: always

    ports:

      - 1808:11808

      - 1443:11443

    volumes:

      - ./caddy:/usr/bin/caddy

      - ./Caddyfile:/etc/caddy/Caddyfile:ro

      - ./caddy-config:/config

      - ./caddy-data:/data

    environment:

      DOMAIN: "https://example.duckdns.org"

      EMAIL: "example@domain.com"
            
      DUCKDNS_TOKEN: "token"

      LOG_FILE: "/data/access.log")`



  

Caddyfile:

' {$DOMAIN}:1443 {

log {

        level INFO

    output file {$LOG_FILE} {

      roll_size 10MB

      roll_keep 10

    }


  

}

tls {

        dns duckdns {$DUCKDNS_TOKEN}


  

}

encode gzip

Notifications redirected to the WebSocket server

reverse_proxy /notifications/hub vaultwarden:3012

Proxy everything else to Rocket

reverse_proxy vaultwarden:11444

}`

Any idea where I'm going wrong?
