Can't create DNS zone(s)

[nofuturekid]

Please forgive my ignorance but I fired up Gravity with with docker compose up and this docker-compose.yaml on a Raspberry Pi 4 with Bookworm

docker-compose.yaml

version: '3.4'

services:
  gravity:
    # Important for this to be static and unique
    hostname: gravity1
    image: ghcr.io/beryju/gravity:stable
    restart: unless-stopped
    network_mode: host
    user: root
    volumes:
      - ./data:/data
    # The default log level of info logs DHCP and DNS queries, so ensure
    # the logs aren't filling up the disk
    logging:
      driver: json-file
      options:
        max-size: "10m"
        max-file: "3"

I can log into Gravity and successfully create DHCP scopes and also users but nothing else.
The gray "Next" button just won't turn blue, same happens for "Join a node"
