Describe the bug
When using the ContainerName feature to control Nginx in another Container, I see the following error message in the Nginx-UI logs:

nginxui-1  | 2026-02-01 13:45:30.235    ERROR   docker/stat_path.go:24  Failed to stat path error request returned 404 Not Found for API route and version http://%2Fvar%2Frun%2Fdocker.sock/v1.51/containers/nginx/archive?path=%2Frun%2Fnginx.pid, check if the server supports the requested API version

My docker-compose.yml includes the

To Reproduce
Steps to reproduce the behavior:

Start Nginx-UI via Compose:

services:
  nginxui:
    image: 'uozi/nginx-ui:latest'
    restart: unless-stopped

    ports:
      # These ports are in format <host-port>:<container-port>
      #- '80:80' # Public HTTP Port
      #- '443:443' # Public HTTPS Port
      - '9000:9000' # UI?

    environment:
      TZ: "Europe/Berlin"
      #NGINX_UI_IGNORE_DOCKER_SOCKET: true
      NGINX_UI_SERVER_PORT: 9000
      NGINX_UI_SERVER_RUN_MODE: release
      NGINX_UI_NGINX_CONTAINER_NAME: nginx

    volumes:
      - ./appdata/nginx:/etc/nginx
      - ./appdata/nginx-logs:/var/log/nginx
      - ./appdata/nginx-ui:/etc/nginx-ui
      - ./var/www:/var/www
      - /var/run/docker.sock:/var/run/docker.sock

Start a Nginx Container via Compose, for example like this:

services:
  nginx:
    image: nginxinc/nginx-unprivileged:latest
    container_name: nginx
    ports:
      - "8080:8080"
    volumes:
      # Main nginx config
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro
      # Site configs
      - ./nginx/conf.d:/etc/nginx/conf.d:ro
      # Optional: logs on host
      - ./nginx/logs:/var/log/nginx
    restart: unless-stopped

Expected behavior
I would expect to see a connection to the Nginx Container.

Info (please complete the following information):

Server OS: Ubuntu Server 24.04 LTS
Server Arch: amd64
Nginx UI Version: 2.3.2
Your Browser: Edge, Chrome and Vivaldi

Additional context
According to the Documentation I got the impression that the only thing I need to do are including the Docker Socket in the Stack and tell Nginx-UI either in the compose file or in the app.ini the name of the nginx Container.
I suspected, that this is an issue with the Docker API version, which recently bumped up their minimum version, which caused issues with other software as well. So I went ahead and lowered the minimum API version of my Docker installation to 1.24, but this did not help.
