隐身模式下的 Nginx 502 错误

Question

我的NGINX服务器遇到了一个奇怪的问题。该网站在浏览隐身时打开并正常运行，但对于任何新的浏览器/会话，我都收到 NGINX 502 错误网关错误。我在错误日志中只有以下内容。

[错误] 2121

#2121：*34 上游在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："域.tld">

配置文件已附加

Answer 1

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:)
