Remote Docker Host not monitored

Hi, I have 3 docker host in my homelab. One of them run WUD, and accessed via local file. Other two are accessed via tcp socket without encryption. Here is config:

version: '3'
services:
  whatsupdocker:
    image: fmartinou/whats-up-docker
    container_name: Whats-Up-Docker
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /volume1/docker/whats-up-docker:/store
    ports:
      - 3000:3000
    environment:
      - TZ=Europe/Rome
      - WUD_WATCHER_SYNOLOGY_SOCKET=/var/run/docker.sock
      - WUD_WATCHER_SYNOLOGY_CRON=10 9 * * *
      - WUD_WATCHER_DOCKER1_HOST=192.168.99.74
      - WUD_WATCHER_DOCKER1_CRON=11 9 * * *
      - WUD_WATCHER_SURVIVAL_HOST=192.168.99.63
      - WUD_WATCHER_SURVIVAL_CRON=12 9 * * *
      - WUD_TRIGGER_PUSHOVER_1_TOKEN=------MY TOKEN------
      - WUD_TRIGGER_PUSHOVER_1_USER=--------MY USER--------
      - WUD_TRIGGER_PUSHOVER_1_SIMPLEBODY=Container $${name} running on $${watcher} have an update available \n
      - WUD_TRIGGER_PUSHOVER_1_PRIORITY=0
      - WUD_TRIGGER_PUSHOVER_1_MODE=batch
      - WUD_TRIGGER_PUSHOVER_1_ONCE=false

When Cron start, I receive notification on SYNOLOGY, the docker.sock one. On other 2 host, there is container that have not an image in docker Hob and raise an error, but other valid container are not checked:

On host docker1 there are container with valid image on dockerhub, but i get.docker1: Cron finished (0 containers watched, 0 errors, 0 available updates), and also for host survival.

I hope I miss something, but I cannot understand what.

Thanks in advance
