I have a "2048 worker_connections are not enough" error in nginx

I have a "2048 worker_connections are not enough" error in nginx looks like something wrong with redirects but I can't figure out what

Here is a config file of Nginx

# Server globals

worker_processes        8;

error_log               /var/log/nginx/error.log;
pid                     /run/nginx.pid;

include /etc/nginx/modules-enabled/*.conf;


# Worker config

        worker_connections  2048;
        use                 epoll;

}
