nginx：110：连接超时

Question

有时在浏览我的网站时，我收到连接超时错误，并且没有从服务器获得任何响应。

我在nginx错误日志文件中的错误如下

*24 client timed out (110: Connection timed out) while waiting for request, client: 182.59.129.85, server: 0.0.0.0:80

清除浏览器的缓存后，它可以正常工作。但经过一段时间的浏览后，问题再次出现。

我的nginx配置文件如下

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
error_log /var/log/nginx-error.log info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
