问题描述：
在服务器上面，部署的nginx服务，端口设置为80，就会报这样的错误：
2017/12/01 14:32:21 [info] 16118#16118: *3 recv() failed (104: Connection reset by peer) while waiting for request, client: 113.118.224.180, server: 0.0.0.0:80
2017/12/01 14:32:24 [info] 16118#16118: *4 recv() failed (104: Connection reset by peer) while waiting for request, client: 113.118.224.180, server: 0.0.0.0:80
2017/12/01 14:32:34 [info] 16118#16118: *5 recv() failed (104: Connection reset by peer) while waiting for request, client: 36.102.239.73, server: 0.0.0.0:80
2017/12/01 14:32:37 [info] 16118#16118: *6 recv() failed (104: Connection reset by peer) while waiting for request, client: 113.118.224.180, server: 0.0.0.0:80
2017/12/01 14:32:40 [info] 16118#16118: *7 recv() failed (104: Connection reset by peer) while waiting for request, client: 113.118.224.180, server: 0.0.0.0:80
如果我们把端口设置为9090（非80端口），我们业务就能正常接收到消息。
目前我们排除了以下原因：
（1）80端口被占用
（2）80端口没有开放

我是18081端口，日志里也报这个错，请问你是怎么解决的啊？

我也不幸遇到这个问题

1 nginx 端口被占用
2 nginx 缓存错误
3 nginx 检查.conf
