NPM fails to start : s6-rc fatal error

Hi there, since the first timeI installed NPM it never started well. After a reboot of my server the container does start but there’s still this weird error :
s6-rc: info: service s6rc-oneshot-runner: starting s6-rc: info: service s6rc-oneshot-runner successfully started s6-rc: info: service fix-attrs: starting s6-rc: info: service fix-attrs successfully started s6-rc: info: service legacy-cont-init: starting s6-rc: info: service legacy-cont-init successfully started s6-rc: info: service prepare: starting s6-rc: fatal: timed out s6-sudoc: fatal: unable to get exit status from server: Operation timed out /run/s6/basedir/scripts/rc.init: warning: s6-rc failed to properly bring all the services up! Check your logs (in /run/uncaught-logs/current if you have in-container logging) for more information.
I have to go to portainer and recreate the container at each of my server reboot so it starts well.
Here’s the steps to reproduce :
use this docker compose and just reboot your device where NPM is installed.
version: '3.8'services:
app:
image: 'jc21/nginx-proxy-manager:latest'
restart: unless-stopped
ports:
- '80:80'
- '81:81'
- '443:443'
volumes:
- /home/louise/docker/NGINX/data:/data
- /home/louise/docker/NGINX/letsencrypt:/etc/letsencrypt 

If anyone has any idea about how to fix s6-rc not working (I don’t even know what it is tbh), I take !

Start with the supplied Docker Compose configuration and the container logs around the s6-rc prepare service after a host reboot. Reproduce the restart behavior and compare it with recreating the container; done means the container starts successfully after reboot without manual recreation and the timeout no longer occurs.
