Possible reason for NGINX 499 error codes

Question

I\'m getting a lot of 499 NGINX error codes. I see that this is a client side issue. It is not a problem with NGINX or my uWSGI stack. I note the correlation in uWSGI log

Answer 1

HTTP 499 in Nginx means that the client closed the connection before the server answered the request. In my experience is usually caused by client side timeout. As I know it's an Nginx specific error code.
