sntp: Clock select failed

[cksrc]

Bringing up the docker with the following docker compose service:

  local-ntp:
    image: cturra/ntp:latest
    container_name: local-ntp
    restart: always
    privileged: true
    ports:
      - 123:123/udp
    environment:
      - NTP_SERVERS=time.google.com
      - LOG_LEVEL=0
      - TZ=Etc/GMT-4

When I try to query the NTP from my host (mac) with sntp -d 192.168.176.2 I get
