<!-- Answer --> To resolve the `ECONNREFUSED` error, ensure the following: 1. **Backend Server is Running**: Verify that the Superset backend server is running and accessible at `http://xxxx:8000`. You can start the backend server with: ```bash superset run -p 8000 --with-threads --reload --debugger --debug ``` 2. **Check Network Connectivity**: Ensure there are no network issues or firewalls blocking the connection between the frontend and backend. 3. **Verify Configuration**: Double-check the configuration in your `webpack.proxy-config.js` to ensure it correctly points to the backend URL: ```javascript const { supersetPort = 8000, superset: supersetUrl = 'http://xxxx:8000' } = parsedEnvArg(); const backend = (supersetUrl || `http://localhost:${supersetPort}`).replace( '//+$/', '', ); // strip ending backslash ``` 4. **Restart Frontend Server**: After verifying the backend is running and the configuration is correct, restart the frontend development server: ```bash npm run dev-server -- --env=--superset=http://xxxx:8000 ``` If the issue persists, check the logs for additional error messages that might provide more insight into the problem <sup>[[1]](https://github.com/apache/superset/blob/master/superset-frontend/webpack.proxy-config.js)</sup><sup>[[2]](https://github.com/apache/superset/blob/master/docker/nginx/nginx.conf)</sup><sup>[[3]](https://github.com/apache/superset/blob/master/docs/docs/contributing/development.mdx)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
