499 Client Closed Request
The 499 error code is not a standard response status code. NGINX introduced this custom status code. NGX_HTTP_CLIENT_CLOSED_REQUEST (499)
When the NGINX web server responds with a 499 status code, it terminated the request as soon as possible and close the client connection. This possibly indicates that the request was taking too long for the server to respond so the client closed the connection early.
