大概率是nginx没启用keepalive导致的。
https://www.workerman.net/doc/webman/others/nginx-proxy.html
这里有nginx配置教程，你参考下，主要是那个keepalive要有

配置的时候完全按照您的官网文档来设置的，keepalive 10240 这个设置项是有的，设置在upstream xxx里面

nginx好像没用https2这个参数

那是我在网上搜的方案，说去掉http2，我就试了一下，发现不行，我就加回来，手一抖多打了一个s，发现保存不了我就改回去了，nginx记录下了这个错误。

查看一下nginx的error日志,看是不是临时目录权限问题

权限直接在项目根目录给了root 777

是nginx的临时目录权限,不是项目的权限,开nginx的错误日志然后重启nginx,
一般你这种吊诡的问题很大原因是因为nginx的指定用户跟命令行运行的用户不一致导致临时目录无法访问而出错

先开nginx的error日志吧,出错了里面应该有详细的报错信息

如果错误日志里有Permission Denied的报错,大概率就是nginx的临时目录权限
