<!-- Answer --> The blank page after login and the 503 errors for static assets (like the logo and favicon) indicate that Superset's frontend assets are not being served correctly. In production, Superset relies on a web server (typically Nginx) or a dedicated static file service to serve these assets—Flask does not handle this by default. If these assets are missing or the web server is misconfigured, the UI will fail to load, resulting in a blank page and 503 errors for static files ([reference](https://github.com/apache/superset/issues/32898), [reference](https://github.com/apache/superset/issues/32324)). Common causes include: the frontend assets were not built or copied into the final deployment, the Nginx (or reverse proxy) configuration is not correctly forwarding or serving the `/static/assets` path, or the static asset build process is still running in the background (especially in Docker setups). To resolve this: - If using Docker, make sure the frontend asset build process is complete before accessing the UI. Check container logs to confirm asset build completion. - If using a custom image or non-standard deployment, ensure that the frontend assets are built (using `npm ci` and `npm run build` in the `superset-frontend` directory) and copied into the correct location before runtime. - Verify your Nginx or reverse proxy configuration is correctly serving `/static/assets` from the right directory or proxying to the correct service ([reference](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docker/nginx/templates/superset.conf.template)). - Double-check that the files like `superset-logo-horiz.png` and `favicon.png` exist in the expected static assets directory. If these steps don't resolve the issue, check your browser console and Nginx/backend logs for additional errors that might point to a misconfiguration or missing files. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
