Nginx 服务器给出 504 错误

Question

我在 WSL、Ubuntu 上使用 nginx 网络服务器。我需要在此服务器上运行 Magento。我可以在哪里或做什么来调整，以便修复 504 错误？我的默认设置是否正确？

请帮忙

2020/10/29 14:15:46 [error] 65#65: *15 upstream timed out (110: Connection timed out) while reading response header from upstream, client: ::1, server: _, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.2-fpm.sock", host: "localhost"

这是我的服务器上的配置文件 /etc/nginx/sites-available/default
