Router Error Codes
List of error codes
Here is the list of error codes emitted by our routing layer:
499 Client Closed Request: client closed the connection before the server answered the request. It is usually caused by client side timeout.
502 Bad Gateway:
- Your application sent an invalid response to our reverse proxy. This error is often sent when your application is abruptly cutting connections.
- This is also the code when all containers are in quarantine. You can distinguish between these two cases based on the context. If you notice multiple consecutive requests returning a 502 error, it probably means one of your application containers is in quarantine.
503 Service Unavailable:
- The application requests queue is full, so the newly incoming request has not been dequeued.
- The application has been stopped by its owner.
- The application has no
webcontainer responding to web requests.
504 Gateway Timeout: application behind the proxy timed out. Your application must accept connections and send the first byte in a limited amount of time.
