Try copying the code using ALT instead of CTRL.

Thanks for response, but how can I use ALT istead of CTRL? It doesn't work on my Windows notebook. I am pasting it to VS Code. When I format it like this

version: '2'
services:
  proxy:
    build: ./
    networks:
      - site1
      - site2
    ports:
      - "80:80"
      - "443:443"

  networks:
    site1:
      external:
        name: site1_default
    site2:
      external:
        name: site2_default
Enter fullscreen mode Exit fullscreen mode

It gives me an error

ERROR: The Compose file '.\docker-compose.yml' is invalid because:
Unsupported config option for services.networks: 'site2'
Enter fullscreen mode Exit fullscreen mode

What is wrong?

Enter fullscreen mode Exit fullscreen mode
