Assets not accessible?

Hi everybody,

I’ve just setup Fabmanager with the docker guide.
Everything is fine but when I try to access the page, I only see:
Powered by Fab Manager

It seems as if the assets don’t get loaded.
I see they are available in the src dir under public/assets.

Can anyone tell me how to debug? It might be an nginx issue. The config is:

upstream puma {
  server fabmanager:3000;

server {
  listen 80;
  server_name openlab
  root /usr/src/app/public;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;

  try_files $uri/index.html $uri @puma;
  location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://puma;

  client_max_body_size 4G;
  keepalive_timeout 10;

  error_page 500 502 504 /500.html;
  error_page 503 @503;

  # Return a 503 error if the maintenance page exists.
  if (-f /usr/src/app/public/maintenance.html) {
    return 503;

  location @503 {
    # Serve static assets if found.
    if (-f $request_filename) {

    # Set root to the shared directory.
    root /usr/src/app/public/;
    rewrite ^(.*)$ /maintenance.html break;

  # no spam bot
  if ($http_referer ~* (|free-share-buttons|social-buttons|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| { return 403; }


Thank you very much!

Hi @chbla,
I’m not an nginx expert but can you tell us what is the console ouput, in your browser, when accessing fab-manager? This may help!

NB: Press Ctrl+Shift+I to open the console
