# Caused by: java.io.IOException: Connection reset by peer #

## 错误描述 ##

系统一直稳定运行，直至在`nginx`中增加`SSL`证书后，突然出现以下问题：

1.  前端异步请求后端数据无法正常返回，但是请求实际上正常，单独请求是可以获取数据的。
2.  部分静态资源（图片、JS）加载异常
3.  服务器后端抛出`Caused by: java.io.IOException: Connection reset by peer`异常
4.  浏览器抛出`net::ERR_CONTENT_LENGTH_MISMATCH`异常

## 解决方案 ##

在`nginx`配置文件中工作进程上增加`user root;`。  
示例：

user root;
    worker_processes 8;

我也不清楚为什么会出现这样的问题
