Deployment error

[riddertommie]

As soon if i try to connect a container (in the same docker-compose file) i get below error in portainer.

Is the feature no supported anymore?

I used with different containers all give the same.

below is a example with curl:

  gluetun:
    image: qmcgaw/gluetun
    container_name: gluetun
    # line above must be uncommented to allow external containers to connect.
    # See https://github.com/qdm12/gluetun-wiki/blob/main/setup/connect-a-container-to-gluetun.md#external-container-to-glue>
    cap_add:

      - 8388:8388/udp # Shadowsocks
    volumes:
      - /opt/gluetun:/gluetun
    environment:

      # - SERVER_COUNTRIES=Belgium
    restart: always
  
  curl:
