GitHub user dosubot[bot] added a comment to the discussion: Self-hosting Superset leads to `ERR_EMPTY_RESPONSE`
<!-- Answer --> I couldn't find a specific solution to the `ERR_EMPTY_RESPONSE` error within the repository, but here are some general recommendations that might help resolve connectivity issues when hosting Superset with Docker: 1. **Network Configuration**: Ensure that all services are correctly configured to communicate within the same Docker network. You are using `superset-network`, which is good. Double-check that all services are indeed connected to this network. 2. **Service URLs**: Verify that the service URLs are correctly set. For internal communication between Docker services, use the service names as hostnames (e.g., `superset-db` for PostgreSQL and `superset-redis` for Redis). 3. **Port Binding**: Ensure that the port binding is correctly set up. You have `8088:8088` for Superset, which should be correct. Make sure no other service is using this port on your host machine. 4. **Environment Variables**: Double-check the environment variables in your `docker-compose.yml` file. Ensure that `SUPERSET_CONFIG_PATH`, `DATABASE_URL`, and `REDIS_URL` are correctly pointing to the respective services. 5. **Command Execution**: The command you are using to start Superset seems comprehensive. However, consider simplifying it to isolate the issue. Start with just `superset run -p 8088` and see if the error persists. 6. **Logs and Debugging**: Check the logs of the Superset container for any errors or warnings that might indicate the cause of the issue. You can do this by running `docker logs superset`. 7. **Docker Image Version**: Ensure you are using a stable version of the Superset Docker image. Sometimes, the latest image might have unresolved issues. Consider using a specific version tag instead of `latest`. If these steps do not resolve the issue, you might want to explore similar threads or discussions for additional insights. For example, there is an open discussion about connecting to a Postgres DB running in a container, which might provide some relevant context <sup>[[1]](https://github.com/apache/superset/discussions/30880)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
