Unreachable under localhost

[CaptainGoldfish]

Hi I just tried to get the server up and running, which seems to work fine, but I cannot manage to access the webadmin of the jellyfin server. I tried to start the server with docker:

Code:

services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin
    user: 1000:1000
    network_mode: 'host'
    ports:
      - 8096:8096
    volumes:
      - K:/jellyfin/config:/config
      - K:/jellyfin/cache:/cache
      - type: bind
        source: K:/my-media
        target: /media
        read_only: true
    restart: 'unless-stopped'

after the server started, I tried to access http://localhost:8096 but I only get a connection refused from the browser. Just as if the port 8096 is not the correct one. What else do I have to do?
