Is there a problem with my network? Is a network in a specific area needed?

Exception: Couldn’t start the app because 'http://127.0.0.1:7860/gradio_api/startup-events' failed (code 503). Check your network or proxy settings to ensure localhost is accessible.

Reproduce the launch from webui/demo_gradio.py at the block.launch call around line 404 and check whether the local /gradio_api/startup-events endpoint returns 503. Verify localhost and proxy or network settings, then confirm that the app starts successfully at the reported local URL.
