Docker instance of Traefik shutting down on it's own

Traefik Traefik v2 (latest)
1

Hey there, i'm setting up my homelab with Traefik, simple reverse proxy from subdomain to internal ports through a docker network, but when i leave my instance of Traefik up for a long-ish period of time it stops itself out of nowhere, here are my docker-compose for traefik, a service i'm running that is proxied by traefik for example of usage and the log at shutdown moment:

Traefik:

version: '3'
services:
  traefik:
    image: "traefik:latest"
    container_name: "traefik"
    command:
      - "--log.level=DEBUG"
      - "--api.dashboard=true"
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.network=reverseproxy-nw"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      
      #- "--entrypoints.websecure.address=:443"

      # cert resolver
      #- "--certificatesresolvers.myresolver.acme.tlschallenge=true"
      #- "--certificatesresolvers.myresolver.acme.caserver=https://acme-v02.api.letsencrypt.org/directory"
      #- "--certificatesresolvers.myresolver.acme.email=email@example.com"
      #- "--certificatesresolvers.myresolver.acme.storage=/letsencrypt/acme.json"
    ports:
      - "443:443"
      - "80:80"
      - "8080:8080"
    volumes:
      - "/home/gustavo/aplications/traefik/letsencrypt:/letsencrypt"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.dashboard.rule=Host(`traefik.domain.com`)"
      - "traefik.http.routers.dashboard.entrypoints=web"
      - "traefik.http.services.dashboard.loadbalancer.server.port=8080"
    networks:
      - reverseproxy-nw
    
networks:
  reverseproxy-nw:
    name: reverseproxy-nw
    external: true

PS: Commented lines are for enabling SSL certificates once i can lay down the foundation and iron out all the "unwanted behaviours".

        ports:
            - '8000:8000'
            - '9000:9000'
        restart: always
        volumes:

I've placed a few lines before so it shows that there are no prior messages that would explain that behaviour.

I've tried to understand what is causing it from the code but my go skills are questionable at best :confused:.

Can you make sure to run the latest release, either by using a release tag or running a docker pull on the latest image.

If the problem still exists, I would open an issue on GitHub.

Thanks for the reply, I forgot about placing the version being used, currently the image is on version 2.9.6.

I thought about opening an issue on GitHub but wanted to make sure it wasn't something obvious I was missing :sweat_smile:. I'll go ahead and open one, thanks!
