Can't find or connect to Home Assistant

[Jiheffe]

Hi,
I have Node-RED and Home Assistant each running in their docker container...
I try to set up the Home Assistant server per these instructions. I can't find the server with the search button, so I configure it manually: http://192.168.2.60:8123.
When I then try to deploy, the box under the node stays on orange Connecting...
In the Node-RED log, I just get

95bf883801cc_nodered | 28 Oct 21:18:49 - [info] Stopped flows
95bf883801cc_nodered | 28 Oct 21:18:49 - [info] Starting flows

This is my Node-RED docker-compose.yml file:

version: "3.7"

services:
  node-red:
    container_name: nodered
    image: nodered/node-red:latest
    environment:
      - TZ=Europe/Brussels
    ports:
      - "1880:1880"
    restart: unless-stopped
    volumes:
      - ./data:/data

And this is my Home Assistant docker-compose.yml:

version: '3'
services:
  homeassistant:
    container_name: homeassistant
    image: homeassistant/home-assistant:stable
    volumes:
      - ./config:/config
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock
    devices:
      # Conbee II Zigbee device on USB
      - /dev/ttyACM1:/dev/ttyACM1
    restart: unless-stopped
    network_mode: host

Can anyone tell me what I am missing ?
