Wordpress-php-fpm中的超时504网关超时nginx

我想在Kubernetes中设置WordPress PHP-fpm，所以我已经进行了设置，但是Nginx代理当前存在一些问题，因此当我尝试安装woo-commerce插件时，它会给出以下错误：

安装失败：504网关超时504网关超时nginx填充，用于禁用MSIE和Chrome友好错误页面-> <！-填充以禁用MSIE和Chrome友好错误页面->

我不知道代理发生了什么问题，我已经为proxy_read_timeout 100设置了最大值。但是那也行不通。我尝试了很多代理超时值，但是没有用，所以这是我的Nginx代理配置
