wordpress - 隐身模式下的 Nginx 502 错误

问题描述

我的 NGINX 服务器出现了一个奇怪的问题。该网站打开并在浏览隐身模式时正常运行，但是对于任何新的浏览器/会话，我都会收到 NGINX 502 Bad Gateway 错误。我在错误日志中只有以下内容。

[错误] 2121#2121: *34 上游从上游读取响应标头时发送的标头太大，客户端：xx.xx.xx.xx，服务器：domain.tld，请求：“GET / HTTP/2.0”，上游：“ fastcgi://unix:/run/php/php7.2-fpm.sock:"，主机："domain.tld"

配置文件已附上

解决方案

通过将以下指令添加到我的 nginx 配置文件来修复它

fastcgi_max_temp_file_size 0;
fastcgi_buffers 128 2048k;
fastcgi_buffer_size 2048k;

希望它可以帮助无法修复此错误的人:)
