[BUG] 502 Bad Gateway when trying to access WebUI (Docker)

Hi, I’m trying to install InvenTree since this morning with docker (Unraid Server), On Unraid, we don’t have the docker compose, so I created two dockers, one containing InvenTree and another containing the Nginx, both are in bridge access. InvenTree was installed without too much difficulty however no way to access the web interface, I get a 502 error and the Nginx logs indicate: "[error] 31#31: *2 connect() failed (111: Connection refused) while connecting to upstream"

Concerning the docker :

• InvenTree
• Nginx

I’ve used the Nginx conf files given on the repo : server { # Listen for connection on (internal) port 80 listen 80; server_name 192.168.0.50; location / { # Change ‘inventree-server’ to the name of the inventree server container, # and ‘8000’ to the INVENTREE_WEB_PORT (if not default) proxy_pass http://192.168.0.50:8181;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;

    proxy_redirect off;

    client_max_body_size 100M;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-Proto $scheme;

    proxy_buffering off;
    proxy_request_buffering off;

}

# Redirect any requests for static files
location /static/ {
    alias /var/www/static/;
    autoindex on;

    # Caching settings
    expires 30d;
    add_header Pragma public;
    add_header Cache-Control "public";
}

# Redirect any requests for media files
location /media/ {
    alias /var/www/media/;

    # Media files require user authentication
    auth_request /auth;
}

# Use the 'user' API endpoint for auth
location /auth {
    internal;

    proxy_pass http://192.168.0.50:8181/auth/;

    proxy_pass_request_body off;
    proxy_set_header Content-Length "";
    proxy_set_header X-Original-URI $request_uri;
}

}
