Docker compose official image + docker nginx reverse proxy : blank page

Hello @Horlogrium , welcome to our community :slightly_smiling_face:

I see a mistake in your docker-compose file, indeed APP_BASE seems correct but you can’t specify it again in the APP_FULL_BASE_URL. Otherwise it will search for fullBaseUrl/appBase/appBase

Also, for /etc/nginx/sites-enabled/nginx-passbolt.conf can you try to add this block:

  location ~* \.(jpe?g|woff|woff2|ttf|gif|png|bmp|ico|css|js|ejs|json|pdf|zip|htm|html|docx?|xlsx?|pptx?|txt|wav|swf|svg|woff2|avi|mp\d)$ {
  access_log on;
  log_not_found on;
  rewrite ^/([^/]+)/([img|css|js|fonts|locales]+)/(.*)$ /$2/$3 break;
  rewrite ^/([^/]+)/favicon.ico$ /favicon.ico break;
  try_files $uri $uri/ /index.php?$args;
}

Could you share a screenshot of what you are seing after these changes when you reach the url?
