I recently decided to self host a few services I had in mind. I thought to start with an old rpi 3 I got laying around. First service I setted up was SMB share with docker compose. After that I wanted to implement wg to access SMB from everywhere. I wanted to do that with docker compose aswell so I went with wg-easy. I went with the simple installation but after i run that, connecting to SMB from gio stopped working. I am not expirienced with any of this. I will upload my files here so that if anyone has any idea what I'm doing wrong to advise me.

my docker-compose.yaml for SMB:

services:
  samba:
    image: dockurr/samba
    container_name: samba
#    network_mode: host
    environment:
      NAME: "Cloud"
      USER: "samba"
      PASS: "<my-pass>"
    ports:
      - 139:139
      - 445:445
    volumes:
      - /mnt/SSD:/storage
#      - ./users.conf:/etc/samba/users.conf
#      - ./smb.conf:/etc/samba/smb.conf
    restart: always 

my docker-compose.yaml for WG:

volumes:
  etc_wireguard:

services:
  wg-easy:
    environment:
    #  Optional:
    #  - PORT=51821
    #  - HOST=0.0.0.0
      - INSECURE=false

    image: ghcr.io/wg-easy/wg-easy:15
    container_name: wg-easy
    networks:
      wg:
        ipv4_address: 10.42.42.42
        ipv6_address: fdcc:ad94:bacf:61a3::2a
    volumes:
      - etc_wireguard:/etc/wireguard
      - /lib/modules:/lib/modules:ro
    ports:
      - "51820:51820/udp"
      - "51821:51821/tcp"
    restart: unless-stopped
    cap_add:
      - NET_ADMIN
      - SYS_MODULE
      # - NET_RAW # ⚠️ Uncomment if using Podman
    sysctls:
      - net.ipv4.ip_forward=1
      - net.ipv4.conf.all.src_valid_mark=1
      - net.ipv6.conf.all.disable_ipv6=0
      - net.ipv6.conf.all.forwarding=1
      - net.ipv6.conf.default.forwarding=1

networks:
  wg:
    driver: bridge
    enable_ipv6: true
    ipam:
      driver: default
      config:
        - subnet: 10.42.42.0/24
        - subnet: fdcc:ad94:bacf:61a3::/64

when i run gio mount smb://samba@<ip>/Cloud

I now get error: Failed to mount Windows share: Connection refused

And after that if I run docker compose ls smb says it is restarting.

I feel like I kind of went randomly to just set this up since I didn't find a well documented source for my usecase and since I'm no expertise to that I messed everything up. Please If you are able to guide me I would really appreciate it. Thanks in advance.

Edit: I was wrong the smb server after a while says restarting I don't know whats at fault. I tried running smb only again but i still had the same issue. I don't remember changing anything else. I don't know what I f*cked up
