The reason is because the client upload file size exceeds the Nginx limit (default is 1M) The official explanation is as follows:

Ps:http 413 Status Code
The server refuses to process the current request because the size of the entity data submitted by the request exceeds the scope that the server is willing or able to handle. 　　In this case, the server can close the connection to prevent the client from continuing to send this request. If this condition is temporary, the server should return a retry-after response header to tell the client how much time it can retry.
