Troubleshooting
Port configuration
If a deployment shows as started but https://<slug>.runex.cloud does not respond, the process may be listening on the wrong port or only on localhost inside the container.
Checklist
- Bind your HTTP server to
0.0.0.0(all interfaces), not only127.0.0.1. - Listen on the port your Runex runtime expects (check the dashboard or current runtime docs for the convention — often provided via
PORT). - For Docker,
EXPOSEthe same port your process uses and ensure theCMD/ENTRYPOINTstarts the server. - Re-read start logs for “address already in use” or immediate exits — see deployment failed.
