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
  • 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 web container responding to web requests
  • 504 Gateway Timeout: application behind the proxy timed out
